Sizing is the silent killer of online fashion.
Your product photography is beautiful. Your descriptions are honest. But shoppers still leave — because they can't picture how a piece will actually fit their body.
Shoppers hesitate between sizes
They open the size chart, close the tab, and never come back.
Wrong sizes create returns
Up to 40% of online fashion is sent back — most of it for fit.
Returns crush your margin
Reverse logistics, restocking, repackaging — every return is a loss.
Confidence wins the sale
If a shopper isn't sure it fits, they don't buy. It's that simple.
A native fit widget that lives on every product page.
SizeFit AI sits quietly next to the size selector. One tap opens a personal fit consultation — built on your size chart, refined by the shopper's measurements, and tuned to the cut of each garment.
- Embedded into your existing product page — no redirects.
- Matches your brand: typography, colors, copy, all editable.
- Returns a clear answer: size, fit style, and confidence score.
- Learns continuously from your catalog and customer feedback.
