Returns
Wrong size. Lost margin.
Size returns are the biggest cost in online fashion. Shoppers guess. They order multiples. They send items back. PrimeStyle AI is designed to address this at the source.
What if every customer could see a size recommendation aligned to their measurements before they ever touched ‘Add to Cart’?
Ship it your way
Four ways to integrate.
SDK and REST API are live today. Widget and Shopify app are next up.
Available today
React & JavaScript SDK
A fully-typed SDK with sizing, smart-size, and virtual try-on components built in. Tree-shakable and framework-agnostic — feels native in Next.js, Vite, Remix, or plain JavaScript. Drop in three components and you have a complete fit experience without writing any UI of your own.
What it does
