Fashion is not a generic e-commerce category. Image performance, drop mechanics, sizing, multi-region pricing and editorial templates all shape the build from day one — and they all break the moment a non-fashion-experienced agency ships them.
Fashion stores live or die by photography. We ship Shopify themes with AVIF/WebP variants, responsive sizes, smart preloading and LCP under 2.5s — even on a 4G connection on the way to the train.
Whether you launch capsules monthly or twice a year, we build the queue, scheduled-publish, password-gated launch and inventory-locking flows that fashion drops actually need.
Fashion is the most global category in commerce. Shopify Markets configured properly, GBP/EUR/USD parallel pricing, hreflang on /uk/, /eu/ and /us/ paths, and tax-included pricing per region.

Themes, UI/UX, SEO, Performance





Custom themes, lookbook templates, drop mechanics, size guides, multi-region setups and the technical-SEO work that keeps fashion stores ranking even when half the page is photography.
Editorial layouts, lookbook templates, hero video, parallax, motion. We build themes that look like the work of an art director rather than a Shopify template tweaked twice.
Per-product size charts, region-aware sizing (US/UK/EU), color/material visual swatches that change the main image, and AI fit-finders integrated where they add real conversion.
Shoppable lookbooks, story-driven landing pages, runway and seasonal templates that the merchandising team can update without involving a developer.
Queue-based releases, password-gated launches, hold-and-release inventory at queue admission, and recovery flows for the seconds-after-sellout traffic spike.
Image SEO, third-party script audit, theme code splitting and Core Web Vitals work that moves the needle on Google ranking and on conversion. Real-user monitoring, not lab numbers.
Linesheet ordering, account-gated price lists, NET30 terms, ERP integration. The B2B feature set on Shopify Plus is mature now — we know which native features to use and which to build around.

Themes, Apps, UI/UX, SEO
Yes — fashion is one of our largest verticals. We have shipped Shopify Plus and standard Shopify stores for Barbosa Fashion (premium menswear), Ruve Shop (contemporary European womenswear), Woolona (premium merino wool), Collegiate Knitwear Designs (university knitwear) and Editiony (luxury limited-edition fashion). Conversion-rate lifts across this roster have averaged +25% post-launch.
Every fashion store we ship uses AVIF and WebP with responsive srcset, lazy-loading below the fold, and the LCP image preloaded with fetchpriority="high". We audit third-party scripts ruthlessly because most fashion stores carry 2–3 chat / review / personalisation widgets that quietly add a second to LCP. Result: mobile LCP typically under 2.5s on a 4G connection.
Yes. We build lookbook templates that the merchandising team can populate without dev involvement — drag-in product picks, hotspots over imagery, and conversion-tracked CTAs. We have shipped this for both monthly editorial drops and seasonal capsule launches.
Depends on the volume. For low-volume launches, scheduled-publish plus a password-gated holding page is enough. For high-volume drops with concurrent-traffic spikes, we layer on queue services (Shopify Plus has native support for some, third-party for others), hold-and-release inventory at queue admission, and bot/scalper mitigation. We have a launch-day playbook we run with the brand the week before.
Yes. Per-product size charts with region-specific tables (US / UK / EU / Asia conversions), measurement guides, and integration with AI fit-finders like True Fit or Bold when the data and budget justify the engagement. We measure impact: well-built size guides typically reduce returns 8–12% and lift CVR.
Yes. We configure Shopify Markets for GBP / EUR / USD / SEK / others as needed, set up hreflang on /uk/, /eu/, /us/ and additional country paths, manage tax-included pricing per region, and integrate with carriers and 3PLs that handle EU and UK customs cleanly. We have done this for European fashion brands selling to the UK, US and beyond.
A custom Shopify theme build for a fashion brand usually sits in the $20K–$60K USD range depending on complexity, integrations (PIM, ERP, OMS) and design scope. Multi-region setups, custom apps and headless storefronts add to that. We provide fixed-scope estimates after a discovery call — no expanding scope mid-project.
A custom theme build is 6–10 weeks. A migration from Magento, BigCommerce or WooCommerce is 10–16 weeks depending on data volume and integration count. Headless Hydrogen builds are 12–20 weeks. We commit to delivery dates after the scoping phase, not before.
