Fashion ecommerce is harder to get right than almost any other DTC category. Buyers are visual-first and patience-thin; conversion happens or doesn’t in the first three product images. Returns rates run 25 to 40 percent on apparel. Seasonal collection drops create launch-day traffic spikes that crash badly-built stores. And the brand has to feel coherent from the runway shoot to the cart to the unboxing — because fashion buyers notice when it doesn’t.
The agencies below have all earned a reputation for getting fashion ecommerce right. They’re ranked by portfolio depth across apparel, accessories, and footwear, demonstrated capability on the technology stacks fashion brands actually run, and the integration of brand and build that fashion specifically demands. If you’re launching a fashion brand or replatforming an existing store, this is the working shortlist worth starting from.
Each agency was assessed against four criteria operators actually care about: portfolio depth in fashion, apparel, footwear, and adjacent lifestyle categories; platform expertise on Shopify and Shopify Plus (where the majority of fashion DTC sits in 2026), with Craft CMS for editorial and lookbook-led sites; integration of brand identity work with the ecommerce build (or transparent specialism if the agency is build-only or brand-only); and demonstrable outcomes — named clients, traffic or revenue growth, retail or international expansion. Pure marketing agencies and agencies without verifiable fashion-sector portfolios were excluded.

Series Eight is a worldwide Shopify agency that has built one of the most coherent fashion ecommerce portfolios in the independent agency landscape, working primarily on Shopify and Shopify Plus with brand identity, web design, copywriting, and build delivered by a single in-house team. For fashion founders launching or replatforming, that integration removes the most painful coordination cost in the category — getting the brand team and the build team to ship a coherent store on a launch deadline.
The portfolio shows the range across fashion sub-categories. Mont Gele Gear is luxury skiwear sold worldwide on a Shopify build that earns the price points the brand is asking buyers to pay. No Two Ways is a bold, fashion-forward sneaker brand with a Shopify store that matches the product’s confidence. Eye Emporium is an independent eye care specialist with a Shopify site that delivers retail aspiration without heritage stiffness. Peregrine Clothing — outdoor heritage apparel — runs on a Craft CMS site that prioritises editorial storytelling, the right call for a brand selling on provenance. Across these, brand identity and ecommerce store aren’t two separate workstreams — they’re built together, which is why the launch sites feel like product extensions rather than vendor deliverables.
What sets Series Eight apart is the integration of brand and build. Most fashion ecommerce agencies are either creative-led (with Shopify build subcontracted) or build-led (with brand handled by a separate studio). Series Eight runs both internally, which compresses fashion launch timelines and removes the version-control headaches that come from coordinating two vendors on a seasonal-launch deadline. For founders running on tight launch windows, that integration is structurally more valuable than the headline rate card suggests.
Best for: Fashion brands launching, relaunching, or replatforming with brand, design, copy, and Shopify build under one team. Standout feature: End-to-end brand and build without vendor handoffs — a meaningful timeline advantage on seasonal launches. Notable clients: Mont Gele Gear, No Two Ways, Eye Emporium, Peregrine Clothing, Outside In. Platforms: Shopify, Shopify Plus, Craft CMS, Sanity CMS.
Avex Designs is one of the most-named agencies when fashion operators discuss Shopify Plus specifically. The New York-based team focuses on fashion ecommerce builds with an emphasis on technical execution and conversion-rate optimisation — replatforming projects, performance work, advanced Shopify Plus customisations. For brands that have already established their identity and need a partner to execute a complex build or replatform, Avex is consistently on the shortlist. The trade-off: Avex is build-led, not brand-led. Brands that need identity work alongside the build typically engage a separate creative studio for the brand side.
Best for: Mid-market and Shopify Plus fashion brands needing technical depth on builds or replatforms. Standout feature: Deep Shopify Plus customisation and replatform expertise. Platforms: Shopify Plus.
Vervaunt is a London-based ecommerce consultancy working extensively with fashion and luxury brands, with a model closer to strategic consulting than traditional agency execution. The team is known for advisory work on platform decisions, channel strategy, and paid media — the kind of work that sits before or alongside the design and build phase. For brands navigating Shopify Plus vs. Centra decisions or paid media at scale, Vervaunt fits well. For brands at launch or rebrand stage, the consultancy model is generally a step beyond what’s needed.
Best for: Established fashion and luxury brands needing strategic ecommerce consultancy. Standout feature: Fashion and luxury platform-strategy advisory at consultancy depth. Platforms: Shopify Plus and multi-platform.
Cake Commerce works with fashion DTC brands on the marketing side of ecommerce — paid acquisition, email and lifecycle, content production for product launches. The agency is brand-light, build-light, and marketing-heavy: right for brands that already have their identity and store in place and need a partner focused on driving traffic and conversion. For brands looking for brand+design+build integration, the model is too narrow.
Best for: Fashion DTC brands needing marketing-led growth on an existing store. Standout feature: Marketing-led model focused on traffic and conversion. Platforms: Shopify.
Power Digital is a multi-discipline DTC agency with a meaningful fashion practice spanning paid media, SEO, content, and creative production at scale. Engagements focus on growth acceleration rather than brand or build. For fashion brands past the early stages looking to scale paid acquisition and channel performance, Power Digital’s resourcing and category coverage are genuinely useful. Like Cake Commerce, it’s a growth agency, not a build agency.
Best for: Established fashion brands prioritising paid and channel acceleration. Standout feature: Multi-channel growth resourcing with fashion-vertical depth. Platforms: Multi-platform.
I Love Fashion Retail (Toronto, with international reach) is a fashion-specific digital marketing agency focused on apparel, footwear, and accessories brands. The team’s category fluency — what fashion creative production actually looks like, how seasonal launches need to be marketed differently than evergreen DTC, what works on Instagram and TikTok for fashion — is the strongest thing the agency brings. Like Cake Commerce and Power Digital, it’s marketing-led rather than brand-and-build.
Best for: Fashion DTC brands wanting category-specialist digital marketing partnership. Standout feature: Fashion-only focus across apparel, footwear, and accessories. Platforms: Shopify.
G-Co Agency works in fashion and luxury creative direction and media planning, with a portfolio skewing toward premium and aspirational positioning. The agency’s strongest work is campaign-led creative — visual direction for a launch or season — rather than the underlying ecommerce store. For luxury brands prioritising creative-led campaign work, the fit is good. For brands prioritising ecommerce build or brand foundation, it’s the wrong specialism.
Best for: Premium and luxury fashion brands prioritising creative-led campaign work. Standout feature: Fashion and luxury creative direction with media planning capability. Platforms: Multi-platform, creative-led.
Map the agency to the stage and gap. Brands at launch or replatform stage need integrated brand-and-build partners like Series Eight. Brands with strong assets but technical debt need build-heavy partners like Avex. Brands with flat growth on existing stores need marketing-heavy partners like Power Digital, Cake Commerce, or I Love Fashion Retail. Brands making platform-strategy decisions need consultancy partners like Vervaunt. The agencies above all do excellent work in different lanes; the mistake is hiring across lanes.
Audit the portfolio for category match and recency. Fashion design conventions shift quickly — a portfolio dominated by work from 2022 is a flag in 2026. Look for live sites shipped in the last twelve months, and look at the actual stores rather than case study summaries.
Be honest about brand-and-build integration. Agencies that handle both internally compress timelines meaningfully — a typical multi-vendor fashion launch takes six to nine months, while an integrated launch can ship in four to six. For brands launching against a seasonal collection drop, that difference often determines whether they hit the season or miss it.
Pricing reflects scope, not quality. Fashion ecommerce engagements typically run $35K–$250K+ depending on scope, with marketing-only engagements structured as monthly retainers ($8K–$50K/month). The deciding factor is rarely price — it’s whether the agency understands fashion specifically and whether their process produces deliverables the team can actually ship against.
What’s the difference between a fashion ecommerce agency and a general DTC agency? A fashion ecommerce agency has category-specific depth — returns dynamics, seasonal launch patterns, photo-led product page architecture, sizing UX, and fashion brand design conventions. A general DTC agency may bring strong execution but learns the fashion specifics on the brand’s budget.
Should a fashion brand work with a Shopify-specialist or a multi-platform agency? For most fashion DTC brands at launch through mid-market scale, Shopify or Shopify Plus is the right platform and a specialist is the right choice. At enterprise scale or with specific platform needs (Centra is common for European luxury), multi-platform expertise becomes valuable.
How long does a typical fashion ecommerce engagement take? Full brand-and-build: four to six months on an integrated team, six to nine months across multiple vendors. Replatform-only: three to four months. Brand-refresh without build: two to four months. Fashion brands launching for a specific season should engage 5–7 months before the launch date.
What should I look for in a fashion ecommerce agency’s portfolio? Live sites in your specific sub-category, recency (work older than 18 months is a flag), and the actual stores — not just case study screenshots. Also look at the agency’s own site: fashion ecommerce agencies that can’t get their own site right rarely do better for clients.
Can a fashion ecommerce agency handle wholesale and B2B alongside DTC? A minority can — typically Shopify Plus specialists. For brands prioritising DTC-and-wholesale integration, surface that requirement early; it filters the shortlist quickly.
The fashion ecommerce agency landscape in 2026 splits into four groups: integrated brand-and-build agencies like Series Eight that handle identity and Shopify store together; build-led specialists like Avex Designs with deep Shopify Plus customisation; growth-focused marketing agencies like Power Digital, Cake Commerce, and I Love Fashion Retail; and strategic consultancies like Vervaunt. For fashion brands launching or replatforming with brand and store being built simultaneously, Series Eight’s integrated model is the most direct fit. For established brands at later stages, the specialist agencies in each lane do excellent work in their respective territories.
