We are a Shopify Partner with 150+ client engagements since 2017, and fashion D2C is our densest Shopify specialisation. We build Shopify themes and headless stacks, Hydrogen or a custom Next.js front end on the Storefront API, for fashion brands where speed, PDP conversion, size-guide depth and app integration decide the outcome. The working stack is Shopify 2.0 themes or Hydrogen, Judge.me or Loox for reviews, Gokwik for COD conversion, Klaviyo for email and Gallabox or AiSensy for WhatsApp. The part that separates a fashion build from a generic one is inventory behaviour. Size curves deplete unevenly, seasons retire whole collections, and a theme that has not been designed for those two facts starts leaking conversion and rankings within a couple of drops.
Shopify fashion theme architecture means a PDP template per category across apparel, footwear and accessories, a variant picker with the size guide available inline rather than buried, reviews above the fold, trust signals covering delivery estimate, return policy and review count, prepaid nudges against COD, and review schema wired so it renders server-side. The app layer is reviews, COD conversion, email, WhatsApp, browser push, search and cart bundling. The recurring speed killers are installed apps nobody uses, uncompressed imagery, externally loaded fonts and theme JavaScript weight. Two fashion-specific build decisions matter more than the app list. Metafields should carry structured garment data such as measurements per size, fabric composition, care instructions and model height and size worn, so the same facts feed the PDP, the size guide, the catalogue feed and the schema from one source instead of being retyped per product. And the theme needs an explicit sold-out and end-of-season state, because deleting retired products is how brands quietly discard the links and rankings those pages had accumulated.
