Fit prediction for clothing retailers
Reduce clothing returns before they happen.
WooChim predicts each shopper's size at the point of sale and shows it right on your product page — so they buy the right size the first time. Plug it into your store in minutes.

(industry data)
Ranges are industry benchmarks and estimates, not guarantees — your results depend on catalog, category mix, and current return rate.
How it works
Three steps. Live in an afternoon.
Install on your store
Add the Shopify or WooCommerce plugin (or one script tag). No replatforming, no developer sprint — most stores are live the same day.
Your shopper picks an item
On any product page, the shopper opens WooChim and enters a couple of details once. It works on tops, bottoms, dresses, outerwear and more.
They get their size — instantly
WooChim returns a clear size recommendation (“Size M — great fit”) and can show the item on them. They add the right size to cart with confidence.
Impact on your store
Every right-size order is margin you keep.
Size-driven returns quietly tax your margin twice — once on the sale you lose, once on the logistics to take it back. WooChim attacks the cause: the wrong-size purchase.
Fewer returns
15–30% potential
Shoppers buy the size that actually fits, so fewer orders bounce back as “wrong size.”
Higher conversion
+5–12% estimated
Sizing confidence removes the #1 reason a browser hesitates at checkout.
Lower logistics cost
per avoided return
Every return you prevent saves return shipping, restocking, and write-down on its way back.
Happier customers
fewer bad first orders
A right-first-time purchase is the difference between a one-time buyer and a repeat one.
See the difference
The same product page, with and without certainty.
“Which size am I?”
- — Shopper guesses, or orders two sizes to be safe.
- — Cart abandoned, or one of the two comes straight back.
- — You eat the return shipping and restocking.
“Size M — great fit.”
- One confident size, chosen on the page in seconds.
- Higher checkout conversion, one item per order.
- Fewer returns, lower logistics cost, repeat buyers.
