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 shopper could see a size recommendation aligned to their measurements before they ever touched Add to Cart?
That's what PrimeStyle AI helps with — reducing guesswork and helping minimize sizing uncertainty so shoppers can buy with more confidence.
Built for Shopify

Native Shopify app. Trained on your sizes.

Returns are the single largest cost in online apparel — and the merchants solving sizing at the product page are pulling decisively ahead. PrimeStyle AI is the native Shopify app that closes the gap: trained on your size chart, live on every product page, and purpose-built for the conversion economics of modern apparel retail.
