A shopper’s size doesn’t stop mattering at checkout. When something comes back through Corso, Norn already knows the size it recommended — so the swap is easy, the reason is captured, and the next shopper gets an even better fit.

Fit is the number-one reason apparel comes back. Putting Norn’s recommendation inside the return changes the outcome three ways.
Roughly 42% of returns are driven by sizing. A confident recommendation on the product page stops a share of them before the order is ever placed.
Corso makes swapping easy. Norn names the size that actually fits, so a shopper keeps the product in the right size instead of asking for their money back.
Every return tells Norn something true about how a product fits. It learns from each one, so your recommendations keep getting sharper — built from your own customers.
A confident size recommendation that stays with the order — so the right fit is never a guess, on the product page or weeks later.
The exchange where a fit can be put right, and the honest reason a product came back — the feedback that makes Norn better.
It recommends off your own chart from your first product — no order history, no network. The Corso loop is how that recommendation keeps improving.
