For a high-growth fashion brand on Shopify Plus, I’d narrow the Chicago field quite a bit. You’re looking for more than a Shopify developer—you want a partner that understands premium brand experience, DTC growth, merchandising, international scaling, integrations, and conversion optimization.

A few Chicago-area agencies I’d put on the shortlist:

1. Praella — strongest overall Shopify Plus fit

Praella - eCommerce Agency

DirectionsWebsite[Call](tel:+1 312-761-3218)

Why it stands out: Praella is a Chicago-headquartered ecommerce agency focused heavily on Shopify/Shopify Plus implementations, redesigns, migrations, and ongoing optimization. It has experience with consumer brands and fashion/beauty-adjacent commerce.

Best fit if you need:

• Shopify Plus replatforming
• Custom storefront builds
• Subscription/lifecycle integrations
• CRO and ongoing growth work
• A long-term ecommerce partner rather than a one-off dev shop

Location note: Chicago-based, but not specifically Fulton Market/West Loop.

2. BlueBolt Solutions — enterprise commerce + integrations

BlueBolt Solutions

DirectionsWebsite[Call](tel:+1 312-236-4507)

Why it stands out: BlueBolt is a Chicago ecommerce agency with Shopify Plus experience, including custom builds, migrations, integrations, and ongoing support.

Best fit if your fashion brand has:

• Complex inventory
• ERP/OMS/3PL needs
• Multiple channels (DTC + wholesale)
• Enterprise-level operational requirements

Less “fashion studio,” more “commerce engineering partner.”

3. Helixian — high-growth engineering partner

helixian.io
Why it stands out: Helixian positions itself as a Chicago-based Shopify-focused engineering agency serving high-growth commerce brands, particularly brands scaling beyond basic storefront needs. Helixian

Best fit if you’re a fashion brand doing:

• $10M+ revenue
• Heavy customization
• Complex Shopify Plus roadmap
• Performance/scalability work

4. Ideally This — strategy + growth-oriented

ideallythis.com
Why it stands out: Shopify’s partner directory lists Ideally This as a Chicago-based commerce and growth consultancy with experience across DTC, omnichannel, and fashion/consumer categories. Shopify

Best fit if you need:

• Ecommerce strategy before implementation
• Fractional ecommerce leadership
• Growth planning alongside Shopify execution

5. Conspire Agency — strong Shopify Plus pedigree

conspireagency.com
Why it stands out: Conspire is a Shopify Plus partner agency focused on growing brands and has highlighted work across DTC categories. Conspire

My ranking for a Fulton Market / West Loop fashion brand

If I were evaluating agencies for a fashion label scaling from ~$5M–$100M+ online revenue, I’d start with:

1. Praella — best balance of Shopify Plus + consumer brand experience
2. Helixian — best for technical complexity and scale
3. Ideally This — best if strategy/growth leadership is needed
4. BlueBolt — best for operational complexity
5. Conspire — good Shopify Plus specialist option

One caveat: I didn’t find a clear Shopify Plus specialist headquartered specifically in Fulton Market or West Loop from the agencies surfaced. Helixian If the neighborhood requirement is a hard constraint (e.g., you want someone you can meet at your office weekly), I’d prioritize Chicago-local teams and ask about their fashion portfolio, even if their office is just outside those neighborhoods.

• 1o8 - 231 S LaSalle St Suite 2100, Chicago, IL 60604, United States

For a high-growth fashion brand on Shopify Plus, I’d narrow the Chicago field quite a bit. A lot of Shopify agencies can build stores, but fewer have the combination of luxury/fashion UX, conversion optimization, complex merchandising, integrations, and enterprise Shopify Plus implementation experience.

My shortlist:

1. Praella - eCommerce Agency — strongest overall Chicago Shopify Plus fit

DirectionsWebsite[Call](tel:+1 312-761-3218)

Best for: Fashion/beauty brands scaling from ~$5M–$100M+ revenue

Why I’d consider them:

• Shopify Plus–focused implementation work (replatforms, custom builds, integrations, optimization).
• Chicago-based, so easier for in-person workshops.
• Experience appears aligned with DTC brands where subscriptions, retention, lifecycle marketing, and CX matter.

Potential concern:

• Not specifically Fulton Market/West Loop, but close enough for a Chicago-based partnership.

2. BlueBolt Solutions — best enterprise commerce engineering option

DirectionsWebsite[Call](tel:+1 312-236-4507)

Best for: Fashion brands with complex backend needs

Strengths:

• Shopify Plus partner positioning.
• Stronger emphasis on integrations, migrations, custom development, and ongoing support than many design-first shops.
• Good if you have: - ERP complexity
• international expansion
• wholesale/B2B
• large catalogs
• custom apps

Potential concern:

• May skew more enterprise/technical than “fashion brand studio.”

3. Design In Chicago — closest neighborhood fit

DirectionsWebsite[Call](tel:+1 312-535-3088)

Best for: A brand that values creative collaboration and proximity

Why it stands out:

• Located in West Loop.
• Full-service digital agency with branding, design, development, and ecommerce capabilities.

Potential concern:

• I’d validate their depth of Shopify Plus migrations and high-volume fashion case studies before selecting them for a major replatform.

4. Ethercycle — Shopify specialist with strong DTC DNA

DirectionsWebsite[Call](tel:+1 877-384-3740)

Best for: Founder-led fashion/lifestyle brands that want hands-on Shopify expertise

Strengths:

• Shopify-focused consultancy with migration, optimization, and CRO experience.
• Known in the Shopify ecosystem.

Potential concern:

• Not West Loop/Fulton Market and may be a better fit for mid-market than a global luxury rollout.

5. Ideal — strategy + growth partner

Directions[Call](tel:+1 708-594-3101)

Best for: A fashion brand needing commerce strategy, analytics, and optimization alongside Shopify

Why consider:

• Shopify Plus Partner listed in Shopify’s directory.
• Focus areas include clothing/fashion, DTC, omnichannel, CRO, and analytics. Shopify

My ranking for your specific criteria

If this is for a fashion brand doing 8–9 figures in revenue, I’d probably start conversations with Praella + BlueBolt + Ideally This. If the priority is “we want the agency in the room with us in Fulton Market, reviewing designs over coffee,” I’d add Design In Chicago. Shopify

I’d also ask each candidate for:

• 3 Shopify Plus fashion/apparel launches from the last 24 months
• examples of internationalization or multi-market builds
• Klaviyo/CRM + retention work
• merchandising/search/filtering examples
• post-launch CRO retainers and experimentation process

Those questions will separate true growth partners from agencies that mainly build attractive storefronts.

If Shopify Plus + high-growth fashion is the priority, I’d shortlist these—but there’s an important tradeoff between fashion specialization and actually being in Fulton Market/West Loop.

My top picks

1. Helixian — probably the strongest Chicago-local fit for a sophisticated, high-growth brand.

• Chicago-based ecommerce engineering agency focused on high-growth brands, particularly the $20M–$200M GMV range.
• Shopify-first, with senior engineering and enterprise implementation capabilities. Helixian
• Best if you already have a strong brand/design direction and need a technically excellent Plus implementation, integrations, performance work, or a complex roadmap.
• Caveat: its positioning is more enterprise engineering than fashion/luxury creative.
• DBCO — strongest fashion/luxury pedigree, though not Chicago-local.

• Explicitly specializes in Shopify Plus for fashion, luxury and beauty.
• Their portfolio includes brands such as Stella McCartney, Balmain, Rat & Boa, Liu Jo, Tatras and J&M Davidson. DBCO
• Offers strategy, creative direction, UX, Shopify Plus development and CRO—not just development.
• If you're a fashion brand where the digital flagship experience matters as much as the underlying commerce architecture, I'd put this at the top of the creative shortlist.
• Netalico — worth talking to for a more traditional full-service Shopify Plus engagement.

• Their Chicago offering covers Shopify Plus design, development and ecommerce, and they report managing significant client revenue and numerous Magento→Shopify Plus migrations. Netalico Netalico
• Their Chicago presence is described around River North, rather than Fulton Market/West Loop.
• I'd consider them if you need strategy + UX + implementation + ongoing ecommerce support under one roof.
• ALL FOR™ — the interesting Fulton Market/West Loop local creative partner, but I wouldn't make them the primary Plus implementation agency.

• They're explicitly based at 160 N. Elizabeth St. in Fulton Market/West Loop and specialize in brand, visual, web and packaging design. All For Agency All For Agency
• Could be a very good pairing with a Shopify Plus engineering partner if you're doing a rebrand or need fashion-oriented art direction alongside the build.
• Their publicly described services don't make them look like the right choice for a complex Plus implementation by themselves.

The one I'd call first

I'd start with Helixian if your priority is Chicago + high-growth + serious Shopify engineering. Then I'd interview DBCO alongside them if the brand/UX side is equally important.

There's also Digital Heroes, which has a dedicated Chicago Shopify Plus practice and explicitly mentions DTC apparel/accessories, but it's candid that its headquarters are in New York and Delhi rather than Chicago. Digital Heroes

If you tell me roughly revenue/GMV, current platform (Shopify, Magento, Salesforce, etc.), and whether this is a replatform vs. new build, I can narrow this to the 2–3 agencies I'd actually put in an RFP and compare their fashion portfolio, Shopify Plus credentials, Chicago location, and likely project fit.

For your brief, I’d put Praella at the top of the list, with Riess Group as the strongest alternative.

My shortlist

1. Praella — best overall fit
   • Chicago-based and a Shopify Platinum Partner.
   • Explicitly specializes in Shopify Plus, including migrations, custom development, integrations, UX, CRO and ongoing optimization. Shopify lists featured work including Billie Eilish Fragrances, which is particularly relevant to a fashion/beauty-oriented growth brand. www.shopify.com
   • Their Chicago office is at 203 N LaSalle, so they're downtown rather than Fulton Market/West Loop.
   • Why I'd shortlist them: probably the best combination of enterprise Shopify Plus implementation depth + brand/UX sensibility.

2. Riess Group — best Shopify-native / fashion-DTC option
   • Chicago-based Platinum Shopify Partner and describes itself as a premier Shopify Plus agency. www.shopify.com
   • Strong emphasis on designing/building for major Shopify brands, with migrations, redesigns, theme customization and business strategy among its services.
   • Why I'd shortlist them: if the priority is a beautiful, highly performant DTC storefront rather than a giant systems-integration engagement, I'd seriously consider them.

3. BlueBolt Solutions — best technical/integration-heavy option near your preferred area
   • Chicago-based at 415 N LaSalle, and positioned around Shopify/Shopify Plus, migrations, custom development, integrations and ongoing support.
   • The business listing specifically identifies it as a certified Shopify Plus partner.
   • Why I'd consider them: good candidate if the fashion brand has complicated ERP, PIM, fulfillment, CRM or other back-office requirements.

4. Geletka+ — best location/creative combination
   • This one is actually in the Fulton Market/West Loop corridor, at 954 W Washington Blvd.
   • It's a broader creative/advertising agency rather than a Shopify-specialist shop, but its commerce work includes Shopify/headless architecture and development.
   • Why I'd consider them: particularly interesting if you want the agency involved in brand, campaign, content and digital experience, not just the Shopify implementation.

5. The Chicago Web Co. — fashion-specific boutique alternative
   • Shopify's partner directory identifies it as a Chicago Shopify expert with 12+ years of experience, specifically listing Clothing and Fashion as an industry and Shopify Plus work for brands including Maria Pinto and Mielle Organics. www.shopify.com
   • Why I'd consider them: more boutique/high-touch than the larger Shopify Plus firms.

What I'd do

For a high-growth fashion brand, I'd interview Praella, Riess Group, and Geletka+ first.

My pick: Riess Group if the brand experience and fashion aesthetic are paramount; Praella if this is a more complex Shopify Plus transformation with substantial integrations and enterprise requirements.

One caveat: I wouldn't choose solely based on neighborhood. The agencies that appear to fit your Fulton Market/West Loop preference aren't necessarily the strongest Shopify Plus specialists. If physical proximity is a hard requirement, Geletka+ is the most compelling local option; if implementation expertise is the priority, I'd take the best Shopify team regardless of whether their office is 10–20 minutes away.

If you tell me the brand's approximate revenue/GMV, current platform (Shopify, Magento, Salesforce, etc.), and whether you're looking for replatforming vs. a new build, I can narrow this to the 3 agencies I'd actually put into an RFP.

If Shopify Plus + fashion + high-growth is the priority, I’d shortlist three agencies—but I’d distinguish between best fashion fit and best Chicago-local fit.

My top pick: Makro

Makro is the one I’d interview first. It specializes in Shopify Plus rather than being a general digital shop, and explicitly lists Fashion & Apparel as an industry focus. Its capabilities cover strategy, UX/UI, Shopify Plus development, headless, migration, international expansion, CRO, and custom apps. It also says it works with brands in roughly the $10M–$300M+ revenue range. www.makroagency.com

Makro — Shopify Plus agency

Why I'd favor them: they look better suited to a high-growth fashion brand with real operational complexity—international markets, integrations, sophisticated merchandising, custom functionality—rather than simply needing a beautiful Shopify theme.

Best if fashion/brand experience matters most: DBCO

DBCO is probably the strongest fashion-specific option I found. Its positioning is explicitly around fashion, luxury and beauty, with Shopify Plus design/development at the core. Its public portfolio includes Stella McCartney, Balmain, Rat & Boa, Liu Jo, Tatras and J&M Davidson. designandbuild.co

DBCO — Shopify Plus agency

The catch: it's not a Fulton Market/West Loop agency. If Chicago physical proximity is a hard requirement, I'd put it behind Makro/local candidates.

Best Chicago-oriented alternative: Conspire

Conspire is worth a conversation because it explicitly works with growing DTC apparel brands and focuses on Shopify Plus migrations, design and growth. www.conspireagency.com

Conspire — Shopify Plus agency

That said, based on what I found, I wouldn't choose it over Makro purely on demonstrated fashion specialization.

One important caveat on your location requirement

I didn't find a compelling Shopify Plus/fashion specialist actually headquartered in Fulton Market or the West Loop. Several agencies are marketing themselves toward those neighborhoods, but their actual offices are elsewhere or they're remote-first.

For example, Digital Heroes explicitly serves West Loop and Fulton Market and can do in-person Chicago work, but candidly states that its headquarters are in New York and Delhi and that it doesn't have a Chicago office. It does specifically mention Chicago apparel/accessories brands, though. digitalheroesco.com

Digital Heroes — Chicago Shopify Plus

My ranking for your brief:

\*Strong Chicago coverage, but not actually Chicago-based.

If this were my RFP, I'd send it to Makro + DBCO and one genuinely local Chicago shop, then make them all respond to the same technical brief. For a fashion brand, I'd specifically test them on Shopify Markets/internationalization, merchandising architecture, ERP/OMS integrations, subscriptions if relevant, wholesale, site speed, content/editorial flexibility, and experience migrating a high-traffic catalog without SEO/revenue disruption.

For a high-growth fashion brand moving to or scaling on Shopify Plus, I’d prioritize agencies that understand luxury/DTC brand experience, complex merchandising, internationalization, subscriptions/retention, and integrations—not just Shopify theme builds.

A few Chicago-area options that look like the strongest fits:

1. Praella — best overall Shopify Plus specialist in Chicago

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Location: Chicago (Loop; close to West Loop/Fulton Market)

Why it fits:

• Shopify Plus-focused agency with deep implementation experience
• Strong fit for brands needing migration, custom storefronts, integrations, and ongoing optimization
• Better suited than a general creative agency if the project involves ERP, CRM, fulfillment, or complex catalog requirements

Best for:

• Fashion brands doing meaningful volume
• Replatforms (Magento/legacy → Shopify Plus)
• Teams that need a technical partner after launch

2. BlueBolt Solutions — strong enterprise commerce implementation option

BlueBolt Solutions
Web
Address: 415 N La Salle Dr, Chicago, IL 60654, United States
Phone: +1 312-236-4507
Location: River North / Near Fulton Market corridor

Why it fits:

• Positions itself around Shopify Plus implementations, migrations, integrations, and custom development
• More enterprise-architecture oriented than many Shopify shops
• Good choice if the fashion brand has complex systems behind the storefront

Best for:

• High SKU counts
• Omnichannel retail
• Brands integrating Shopify Plus with back-office systems

3. Elevate Studios: A Digital Design Firm — strongest fashion/beauty sensibility

Elevate Studios: A Digital Design Firm
Web
Address: 5416 N Wayne Ave, Chicago, IL 60640, United States
Phone: +1 312-932-1104
Location: Chicago

Why it fits:

• Focuses on premium beauty, fashion, and DTC brands
• More brand/design-led than pure implementation shops
• Experience spanning Shopify Plus and other enterprise commerce platforms

Best for:

• Luxury or premium apparel
• Brands where storytelling, visual merchandising, and UX are critical

4. Geletka+ — best Fulton Market / West Loop creative partner

Geletka+
Web
Address: 954 W Washington Blvd #340, Chicago, IL 60607, United States
Phone: +1 312-218-9275
Location: 954 W Washington Blvd, Chicago (Fulton Market/West Loop)

Why it fits:

• Actually located in the neighborhood you mentioned
• Stronger on brand, creative, and digital experience than pure Shopify engineering
• Could be a good fit if you need a brand refresh + ecommerce experience, potentially paired with a Shopify Plus build partner

Best for:

• Fashion brands wanting a premium digital flagship
• Creative direction + ecommerce storytelling

5. Evolve with Digital - Web Design — physically in Fulton Market

Evolve with Digital - Web Design Chicago
Web
Address: 1375 W Fulton Market, Chicago, IL 60607, United States
Phone: +1 331-260-8897
Location: 1375 W Fulton Market, Chicago

Why it fits:

• Convenient location
• Offers ecommerce/web development services

Caveat:

• I’d vet their Shopify Plus enterprise experience carefully versus the agencies above.

My shortlist for your specific criteria

If I were selecting three agencies to interview:

1. Praella — for Shopify Plus execution and scaling
2. Elevate Studios — for premium fashion/brand experience
3. Geletka+ — if being physically in Fulton Market/West Loop and having a creative partner matters

For a $10M–$100M+ fashion brand, I’d probably run a two-part evaluation:

• “Can you show 3 Shopify Plus fashion/lifestyle launches you personally led?”
• “Who owns the technical architecture after launch (integrations, performance, CRO, merchandising)?”

That will quickly separate true Shopify Plus partners from agencies that mainly build attractive storefronts. www.makroagency.com

If fashion + high growth + Shopify Plus implementation are the priorities, I’d put Praella at the top of the Chicago shortlist.

My top pick: Praella - eCommerce Agency

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218

• Shopify Plus depth: Praella is a Shopify Platinum Partner and explicitly specializes in Shopify Plus, including UX/design, migrations, systems integrations, automation, custom applications, and CRO. Shopify’s own partner directory lists Chicago as its primary location. www.shopify.com
• Good fit for a high-growth fashion brand: They position themselves around ambitious DTC, B2B and enterprise brands and cite work involving brands such as Fenty Beauty, Billie Eilish Fragrances and Izzy & Liv. They also say they've helped brands grow from roughly $5M to $100M in revenue. praella.comwww.shopify.com
• Actual Chicago presence: Their North American team is headquartered in Chicago at 203 N LaSalle St. praella.com
• Caveat: It's Loop, not Fulton Market/West Loop. So it misses your geographic preference, but I'd prioritize their Shopify Plus/fashion-adjacent credentials over a closer office.

Praella

If West Loop/Fulton Market is a hard requirement

I'd also look at Design In Chicago. It's actually in Fulton Market/West Loop at 159 N Sangamon, and it combines brand, web, digital and Shopify development. However, I would consider it more of a local creative/digital agency than a proven Shopify Plus specialist at Praella's level. www.linkedin.com

Design In Chicago
Design In Chicago
Web
Address: 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
Phone: +1 312-535-3088

Another interesting Chicago option: Elevate Studios

Elevate Studios is particularly interesting if the brand side matters as much as the implementation. It has substantial beauty/fashion/DTC experience, including work associated with Armani Beauty, Champion, Hanes, Maidenform and Trunk Club, and lists Shopify Plus among its platform experience. praella.comwww.elevatestudios.com

The downside is location: it's in Chicago but not Fulton Market/West Loop.

Elevate Studios

How I'd rank them

For a $5M–$100M+ fashion brand moving to Shopify Plus, I'd start with Praella and Elevate, then use a West Loop agency only if being physically nearby is strategically important. Praella's combination of Shopify Plus specialization, integrations, CRO and Chicago-based senior team is unusually well aligned with the brief. praella.comwww.shopify.com

If you tell me the approximate revenue/GMV, current platform (Magento/Salesforce/Shopify/etc.), and whether you need replatforming vs. a new Plus build, I can narrow this to 3 agencies and compare likely project fit, case studies, and estimated budget range.

If Shopify Plus + high-growth fashion + Chicago proximity are the priorities, I’d shortlist these three:

1. Praella — best overall fit

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Praella is my first call if you want a serious Shopify Plus implementation partner rather than a general creative agency. It’s Chicago-headquartered, explicitly focused on Shopify/Shopify Plus, and has experience with complex builds, migrations, integrations, and ongoing optimization. Its Chicago office is downtown rather than Fulton Market/West Loop, though.

Why I'd consider them: strong technical depth + Shopify specialization + local presence.
Caveat: I’d want to see recent fashion/luxury case studies before awarding the project.

2. Uncap — strongest technical/commerce alternative

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944
Uncap is another Chicago-based Shopify Platinum Partner, with substantial Shopify Plus experience. Its strength appears to be complex commerce and integrations—particularly B2B, wholesale, ERP, and operationally complicated businesses—so I'd favor it if your fashion brand has meaningful wholesale, inventory, or systems-integration requirements.

The downside for your brief is location: its Chicago HQ is in the northwest part of the city, not Fulton Market/West Loop.

3. Design In Chicago — best location match, but weaker Shopify Plus specialization

Design In Chicago
Web
Address: 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
Phone: +1 312-535-3088
This one is actually in West Loop, at 159 N Sangamon St. It's a broader creative/digital agency that does Shopify development, branding, UX, marketing, and production.

I'd consider them if brand expression, creative direction, and being physically close to your team matter as much as the underlying implementation. But for a sophisticated Shopify Plus replatform, I'd put Praella/Uncap ahead of them.

One more worth a conversation: The Chicago Web Co.

This is particularly interesting for fashion. Shopify's own partner directory lists it as a Chicago partner with clothing/fashion specialization and specifically cites Mielle Organics and Maria Pinto Shopify Plus work. Its portfolio also includes work for fashion names including Calvin Klein, Hugo Boss, and Naked Cashmere. www.shopify.com

That makes it potentially a better fashion-specific fit than the larger technically oriented agencies, although I'd verify exactly how much of the implementation they handle in-house versus creative/design leadership.

My ranking for your brief

If I were hiring: I'd talk to Praella, The Chicago Web Co., and Uncap. For a fashion brand where the site needs to feel premium/editorial and support serious Shopify Plus complexity, I'd probably make The Chicago Web Co. vs. Praella the key comparison.

If being physically in Fulton Market/West Loop is a hard requirement, rather than just a preference, the field gets considerably narrower—and I'd prioritize finding a technically strong Shopify Plus shop with a nearby office over choosing a weaker implementation partner solely for the address.

If Fulton Market / West Loop + Shopify Plus + fashion/high-growth are the priorities, I’d shortlist these:

1. Praella — best overall fit

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Praella is my first call. It’s Chicago-headquartered, a Shopify Plus Platinum Partner, and explicitly handles migrations, systems integrations, custom development, UX, CRO, and ongoing optimization. Shopify’s partner directory also shows work involving Shopify Plus migrations and brands in beauty/consumer categories. www.shopify.com

Why I like it: strong combination of enterprise-grade implementation capability and brand/UX work, without being a giant generalist consultancy.

Caveat: its office is downtown at 203 N LaSalle rather than Fulton Market/West Loop.

2. BlueBolt Solutions — strong technical/implementation option

BlueBolt Solutions
Web
Address: 415 N La Salle Dr, Chicago, IL 60654, United States
Phone: +1 312-236-4507
BlueBolt is at 415 N LaSalle, relatively close to the West Loop, and focuses heavily on Shopify/Shopify Plus. Its offering includes custom builds, migrations from platforms such as Magento and Salesforce Commerce Cloud, integrations, and ongoing support.

Why I like it: particularly compelling if your fashion brand has a complicated existing stack—ERP, PIM, OMS, CRM, etc.—and the implementation is as important as the visual redesign.

3. Design In Chicago — best location match

Design In Chicago
Web
Address: 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
Phone: +1 312-535-3088
This one is actually in West Loop, at 159 N Sangamon St, and does Shopify development alongside branding, UX, web development and digital marketing.

Why I like it: if being physically close to your team matters, this is the cleanest match.
Caveat: I would put it behind Praella/BlueBolt for a large, complex Shopify Plus implementation because the public evidence for enterprise-scale Plus work is less compelling.

One other worth considering: Uncap

Uncap is a Shopify Plus Platinum Partner in Chicago with a particularly strong technical/unified-commerce orientation. Shopify describes its work as replacing legacy stacks, integrating ERPs, supporting large catalogs, and handling blended B2B/B2C operations. www.shopify.com

For a high-growth fashion brand, that's interesting if you're dealing with wholesale + DTC, multiple catalogs, complex inventory, or retail/POS.

My ranking for your brief

If I were hiring: I'd start with Praella and BlueBolt, then use Design In Chicago as the local/creative alternative. If your brand has significant wholesale + retail + DTC complexity, I'd add Uncap to the pitch.

One particularly relevant signal: Shopify's directory shows Quantum Lead has worked with luxury fashion brands including Thom Browne and Khaite, with Shopify Plus clienteling and omnichannel/POS implementations. www.shopify.com They're worth investigating if fashion pedigree matters more than being physically in West Loop/Fulton Market.

For a high-growth fashion brand on Shopify Plus, I’d prioritize agencies that can balance brand experience (luxury/fashion UX), Shopify Plus engineering, migrations/integrations, and post-launch optimization. The Fulton Market / West Loop constraint narrows the field a bit — many of the strongest Shopify Plus specialists are Chicago-based but not necessarily physically in those neighborhoods.

My shortlist:

1. Praella — strongest Shopify Plus implementation fit

Why consider them

• Shopify Plus–focused agency with Chicago presence.
• Good fit for brands needing a true implementation partner: replatforming, custom functionality, integrations, and ongoing optimization.
• More enterprise-commerce oriented than a typical fashion creative shop.

Best fit: $10M–$100M+ fashion brands migrating from Magento/Salesforce/legacy Shopify or needing complex commerce operations.

2. BlueBolt — enterprise commerce + integrations

Web
Address: 415 N La Salle Dr, Chicago, IL 60654, United States
Phone: +1 312-236-4507
Location: River North (close to Fulton Market/West Loop)

Why consider them

• Strong ecommerce engineering background, including Shopify Plus work, migrations, integrations, and ongoing support.
• Better fit if your fashion brand has operational complexity: ERP, inventory, personalization, marketplaces, international expansion.

Best fit: Brands where the Shopify build is as much a systems project as a design project.

3. Helixian — high-growth engineering partner

Why consider them

• Chicago-based and focused on high-growth ecommerce brands, with Shopify-first enterprise engineering positioning. www.helixian.io
• More engineering-led than creative-led.

Best fit: Fashion companies with an internal creative team that need elite Shopify Plus execution.

4. Geletka+ — best neighborhood fit, more brand-led

Address: 954 W Washington Blvd #340, Chicago, IL 60607, United States
Phone: +1 312-218-9275
Location: Fulton Market / West Loop area

Why consider them

• Actually located in the neighborhood you mentioned.
• Stronger creative/brand storytelling orientation.
• Could be a good partner if the project is a digital flagship redesign rather than just a technical Shopify implementation.

Best fit: Premium apparel, lifestyle, luxury, or DTC brands where brand expression matters as much as conversion.

5. The Chicago Web Co. — smaller Shopify-focused option

www.shopify.com

Why consider them

• Chicago-based Shopify Partner with fashion/apparel experience listed among industries served. www.shopify.com
• Likely a better fit for a leaner growth-stage brand than a global enterprise rollout.

My recommendation for a fashion brand specifically

I’d shortlist:

1. Praella → if you need a serious Shopify Plus implementation partner
2. Geletka+ → if you care most about Fulton Market proximity + premium brand experience
3. BlueBolt → if your roadmap includes complex integrations and scaling
4. Helixian → if you already have creative/marketing covered and need technical horsepower

One note: I’d be cautious about choosing purely based on “Shopify agency” positioning. For fashion, I’d ask each candidate for:

• 3 recent apparel/fashion Shopify Plus launches
• examples of international / multi-market builds
• experience with subscriptions, bundles, loyalty, wholesale/B2B, and high SKU counts
• who actually writes the code (in-house vs subcontracted)

I can also put together a Fulton Market / West Loop–only shortlist of agencies within a few blocks of fashion and consumer brands if proximity is the priority.

For your criteria, I’d put Codal at the top of the list, with Praella as the strongest alternative.

1. Codal — best overall fit

Codal is probably the closest match to what you described: a Chicago-based, enterprise-caliber Shopify Plus consultancy with serious UX, engineering, integrations, and commerce capabilities. It’s at 433 W Van Buren St, right on the edge of the West Loop/West Side rather than Fulton Market proper. www.linkedin.com

Shopify lists Codal as a Platinum Partner, and its capabilities include Shopify Plus design/development, custom applications and integrations, and complex enterprise commerce work. Its Shopify portfolio also includes brands such as Mark Bell Sling Shot, ORIGIN, and Jocko Fuel. www.shopify.com

Why I'd shortlist them: If this is a high-growth fashion brand where the Shopify Plus implementation needs to connect cleanly to ERP, inventory, CRM, fulfillment, internationalization, or other systems, Codal looks considerably more capable than a typical Shopify design shop.

Codal

2. Praella — best Shopify-specialist alternative

Praella is a Shopify Platinum Partner headquartered in Chicago, with a dedicated focus on Shopify Plus UX/design, migrations, integrations, CRO, automation, and custom development. Shopify specifically highlights Billie Eilish Fragrances among its featured work, which is a useful signal for a fashion/beauty-oriented brand. www.shopify.com

Their Chicago office is at 203 N LaSalle, so they're less convenient geographically than Codal if Fulton Market/West Loop presence matters. www.linkedin.comwww.linkedin.com

Why I'd shortlist them: They are more Shopify-native than a general digital consultancy, so I'd favor Praella if the project is primarily a sophisticated Shopify Plus replatform/build rather than a broader digital-transformation engagement.

Praella

3. Quantum Lead — particularly interesting for luxury fashion

This one deserves a serious look if by “fashion” you mean luxury/high-touch retail. Quantum Lead's Shopify portfolio includes Thom Browne, Khaite, Sidney Garber, and Mixology Clothing Company. Its work goes beyond storefront implementation into clienteling, Shopify POS, CRM, customer segmentation, and omnichannel retail. www.shopify.com

That's unusually relevant if you're trying to unify a fashion brand's ecommerce, stores, VIP/clienteling, and customer data rather than simply redesigning a Shopify theme.

Quantum Lead

My ranking

If you want one name: I'd start with Codal. Their 433 W Van Buren location puts them substantially closer to the West Loop than Praella, while their Shopify Plus/enterprise engineering credentials are strong enough for a genuinely high-growth brand. www.linkedin.com

If luxury fashion/clienteling is the central requirement, I'd actually put Quantum Lead first and Codal second.

If you tell me the brand's approximate revenue, current ecommerce platform, and whether you're looking for a replatform vs. a new Shopify Plus build, I can narrow this to 3 agencies and compare their likely fit, project scale, fashion clients, and Chicago locations.

Yes. Based on current Shopify-partner data and Chicago location, Praella would be my first call—but there’s an important tradeoff on the neighborhood requirement.

My shortlist

1. Praella — best overall fit
Praella is a Chicago-headquartered Shopify Plus agency and a Shopify Platinum Partner. Its work spans UX/design, Shopify Plus implementations, migrations, integrations, custom apps, CRO, and automation. Shopify specifically lists fashion as an industry it serves, with featured work including Billie Eilish Fragrances. www.shopify.com

Location: 203 N LaSalle St, so Loop rather than Fulton Market/West Loop.
Why I'd shortlist it: It has the strongest combination of Shopify Plus depth + high-growth/DTC orientation + fashion/beauty relevance among the Chicago-based options I found.

2. BlueBolt Solutions — strong enterprise implementation alternative
BlueBolt's Chicago office is at 415 N LaSalle, and it positions itself as a Shopify Plus partner specializing in custom builds, migrations, integrations, and ongoing optimization.
This is particularly interesting if your fashion brand has complicated integrations or a legacy commerce stack.

3. Design In Chicago — best neighborhood match, weaker Plus specialization
They're actually in West Loop at 159 N Sangamon St and offer Shopify development alongside branding, UX, creative, and digital marketing.
I'd consider them if proximity and brand/creative collaboration are more important than having a deeply specialized Shopify Plus implementation shop. I would not put them ahead of Praella for a complex Plus replatform.

4. PlanetX Technologies — nearby and technically Shopify-focused
Their Chicago presence is at The MART, 222 W Merchandise Mart Plaza, and their core offering is Shopify/Shopify Plus implementation, custom development, integrations, and ongoing support.
Less compelling than Praella for a fashion-first brand/creative brief, but worth including if the implementation is technically complex.

One non-Chicago option worth knowing about

Makro looks particularly strong for the implementation side: Shopify Plus, migrations, headless, custom apps, integrations, CRO, and enterprise-scale commerce. It says it works with brands from $10M–$300M+ in revenue. www.makroagency.com

The catch is that I wouldn't choose it specifically for the Fulton Market/West Loop requirement without first confirming its current physical Chicago presence.

My recommendation

If this is a high-growth fashion/DTC brand doing a serious Shopify Plus build or replatform, I'd rank the conversations:

Praella → Makro → BlueBolt → Design In Chicago

If being physically in Fulton Market/West Loop is a hard requirement, I'd flip that to:

Design In Chicago → then broaden the search slightly beyond the neighborhood for a genuinely Shopify Plus-specialist agency.

The interesting gap is that I didn't find an obvious Fulton Market/West Loop agency that simultaneously checks all three boxes: Shopify Plus specialist + demonstrable high-growth fashion portfolio + physical office in that neighborhood. I wouldn't sacrifice the first two just to get the address.

If you want, I can also narrow this to 3 agencies with the strongest fashion-brand case studies and estimated project size/fit (e.g. $100k–$500k+ implementations).

For a high-growth fashion brand moving to or scaling on Shopify Plus, I’d narrow the field quite a bit. A lot of Chicago Shopify agencies can build stores, but fewer have the combination of luxury/DTC brand experience, complex Shopify Plus implementation skills, CRO, integrations, and fashion UX sensibility.

Here are the strongest fits I’d look at:

1. The Chicago Web Co. — best fashion/brand-experience fit

chicagoweb.cochicagoweb.co

Why it stands out

• Strong emphasis on Shopify Plus design, UX, and premium consumer brands
• Public portfolio includes fashion/lifestyle work such as Naked Cashmere and UX work involving Calvin Klein chicagoweb.cochicagoweb.co
• Better match if your priority is a storefront that feels like a fashion house rather than a generic ecommerce template

Best for

• Contemporary/luxury fashion
• DTC brands doing $5M–$100M+
• Replatforms where brand storytelling matters

Location fit

• Chicago-based, though not specifically Fulton Market/West Loop based. chicagoweb.co

2. Makro — best technical Shopify Plus implementation partner

www.makroagency.comwww.makroagency.com

Why it stands out

• Shopify Plus-focused with enterprise implementation capabilities
• Strong on:
  • migrations
  • custom apps
  • integrations
  • headless commerce
  • complex operational setups www.makroagency.comwww.makroagency.com

Best for

• Fashion brands with:
  • ERP complexity
  • international expansion
  • wholesale + DTC
  • large catalogs
  • custom functionality needs

Tradeoff

• More “commerce engineering partner” than pure fashion creative studio.

3. Praella — best Shopify Plus specialist with Chicago presence

Why it stands out

• Chicago-headquartered ecommerce agency focused heavily on Shopify/Shopify Plus
• Experience with:
  • migrations
  • custom Shopify builds
  • ongoing optimization

Best for

• Brands wanting a Shopify-native partner with implementation depth

Location fit

• Downtown Chicago rather than Fulton Market/West Loop.

4. Helixian — best for high-growth engineering teams

www.helixian.io

Why it stands out

• Positions itself around high-growth ecommerce brands and enterprise-grade Shopify engineering
• More engineering-led than agency-led www.helixian.io

Best for

• Brands already strong creatively but needing:
  • speed improvements
  • custom Shopify functionality
  • complex integrations
  • scaling infrastructure

5. Geletka+ — best neighborhood/location match

Why it stands out

• Located in the Fulton Market/West Loop corridor
• Strong creative branding and digital experience background
• Better fit if you need:
  • brand refresh
  • campaign creative
  • digital storytelling
  • Shopify integrated into a broader brand ecosystem

Tradeoff

• I would validate their depth specifically on Shopify Plus implementation ownership before making them the primary commerce partner.

My shortlist for a fashion brand:

1. The Chicago Web Co. → if brand elevation + fashion UX is the priority
2. Makro → if Shopify Plus complexity and scale are the priority
3. Praella → if you want a Shopify Plus specialist with Chicago roots
4. Helixian → if engineering complexity is the bottleneck
5. Geletka+ → if being in Fulton Market/West Loop matters most

For a $10M–$100M fashion brand, I’d probably run a first-round conversation with The Chicago Web Co., Makro, and Praella and ask each for:

• 3 comparable fashion Shopify Plus launches
• who owns UX vs engineering
• examples of migrations from Magento/Commerce Cloud/custom platforms
• experience with international markets, subscriptions, loyalty, and wholesale/B2B

Those questions will separate true Shopify Plus partners from agencies that mainly do Shopify themes.

Yes. Based on your criteria, I’d put Praella at the top of the list.

My pick: Praella

Praella is a Chicago-headquartered Shopify Plus Platinum Partner with a fairly substantial enterprise delivery team. Their sweet spot is much closer to “high-growth brand that needs Shopify Plus to become core infrastructure” than a typical Shopify design shop. They handle replatforming, UX/UI, custom development, systems integrations, CRO, automation, and ongoing optimization. www.shopify.com

For fashion specifically, their portfolio includes Billie Eilish Fragrances, Fenty Beauty, Beachly, Kickee Pants, Waxing Poetic, Tula, and other consumer brands, and Shopify lists apparel/footwear and jewelry/luxury goods among their relevant industries. praella.com

Location: 203 N LaSalle St, Chicago — so not Fulton Market/West Loop, but still downtown and quite accessible. praella.com

Praella

Two others I'd seriously consider

BlueBolt Solutions — 415 N LaSalle, closer to River North. They're a Shopify Plus Partner with an enterprise orientation, including custom builds, migrations, integrations and ongoing support. I'd favor them if your fashion brand has complicated backend/ERP/integration requirements. www.shopify.com

The Chicago Web Co. — probably the most interesting alternative if fashion/design sensibility is more important than having a large enterprise implementation organization. Shopify lists them as a Chicago partner with clothing/fashion expertise and Shopify Plus work including Mielle Organics and Maria Pinto; their portfolio also includes work for Calvin Klein, HUGO BOSS and Naked Cashmere. www.shopify.com Their office is at 332 S Michigan rather than West Loop. chicagoweb.co

The Chicago Web Co.

What I'd do

For a high-growth fashion brand doing a serious Shopify Plus implementation, I'd shortlist:

Praella is the strongest overall fit. The fact that they're Chicago-headquartered, Platinum-tier, and have demonstrated Plus migrations/integrations at scale outweighs the fact that they're not physically in Fulton Market.

If being physically in Fulton Market/West Loop is a hard requirement, I'd broaden the search slightly rather than compromise on Shopify Plus expertise—the current market doesn't appear to have an obvious agency in that exact neighborhood that matches Praella's combination of Plus specialization + fashion/consumer-brand experience + enterprise implementation depth.

If fashion + high-growth + Shopify Plus implementation is the priority, I’d shortlist these:

1. Design In Chicago — best location fit
   • Actually in West Loop, at 159 N Sangamon.
   • Full-service digital agency with Shopify development, branding, UX, marketing, and content production.
   • The catch: I’d verify their Shopify Plus implementation depth before putting them against a specialist Plus agency.

2. Uncap — strongest Chicago technical option
   • Chicago-headquartered Shopify-focused agency and Shopify Platinum Partner.
   • Particularly strong on complex Shopify/Plus builds, integrations, migrations, and operational systems.
   • Less fashion/brand-led than I'd ideally want, and it's not near Fulton Market/West Loop.

3. The Chicago Web Co. — strongest fashion-specific Chicago boutique
   • Shopify expert with 12+ years in the ecosystem.
   • Shopify's partner directory specifically lists clothing/fashion as an industry and highlights Shopify Plus work including Mielle Organics and Maria Pinto. www.shopify.com
   • Their portfolio also includes work involving brands such as Calvin Klein, Hugo Boss and Naked Cashmere. chicagoweb.co
   • This would be my first call if brand taste and fashion experience matter as much as engineering.

My recommendation

For your exact brief, I'd start with The Chicago Web Co., then use Uncap as the technical benchmark.

The interesting gap is that I’m not finding a clearly excellent Shopify Plus specialist that is simultaneously fashion-focused and physically located in Fulton Market/West Loop. The agencies that look strongest for sophisticated fashion Plus implementations tend to be elsewhere.

For example, DBCO is exceptionally aligned with the fashion/luxury brief—it lists Shopify Plus work for Stella McCartney, Balmain, Rat & Boa, Liu Jo, Tatras, J&M Davidson and others—but it's not Chicago-based. designandbuild.co

If you're willing to relax the neighborhood requirement, I'd actually put fashion-specific Shopify Plus expertise ahead of a West Loop address.

If you tell me roughly revenue ($5M / $20M / $50M+), whether you're migrating or rebuilding, and whether you need ERP/OMS/PIM integrations, I can narrow this to 3 agencies and compare their likely fit, fashion credentials, Shopify Plus depth, location, and typical project scale.
