The aim is fewer surprises at delivery. When shoppers can't judge how something will sit on them, they order two sizes and send one back, or don't order at all. Try-on narrows that gap by showing the same product across different bodies, skin tones and heights.
There are two kinds. Interactive try-on runs on the store page and places the product on the shopper's own camera feed or photo. Image-based try-on shows each product on a range of models, so a shopper picks the one closest to them. It is close kin to model swap, which re-casts an existing photo.
