OptiDress vs Genlook: try-on on an avatar, or on a photo?
OptiDress and Genlook both let a fashion store's visitors see a garment worn before buying. The difference lies in the mechanism: Genlook generates the image from a photo uploaded by the visitor; OptiDress builds a digital twin from their physical characteristics, without any photo. This page compares both solutions factually. Information verified in August 2026 from each vendor's public communications.
The photo, or no photo at all.
Genlook works by upload: visitors add a photo of themselves (or take a selfie), and the tool generates within seconds an image of the garment worn on that photo. The approach is quick to set up for the merchant, and the visual result is immediate for visitors willing to provide a photo. Photos are automatically deleted after 7 days: for any new session beyond that period, the visitor starts over.
OptiDress asks for no photo. Visitors provide their physical characteristics (height, weight, body type and, if they wish, their measurements) and their digital twin is generated within seconds, then kept for 30 days on the store. This choice answers two structural limits of the photo: not every visitor is willing to photograph themselves while shopping, and a photo does not contain the body data needed for a precise size recommendation. That declared-data foundation is what lets OptiSize recommend the size to order, product by product.

Frequently asked questions.
Do OptiDress and Genlook do the same thing?
Both belong to virtual try-on for online fashion, but the mechanism differs: Genlook generates the image from an uploaded photo; OptiDress builds a digital twin from the visitor's physical characteristics, without any photo, and pairs it with a size recommendation.
Why doesn't OptiDress ask for a photo?
Because a photo limits usage (not every visitor is willing to photograph themselves while shopping) and does not contain the body data needed to recommend a size precisely. Declared characteristics enable both: visualisation and recommendation.
Do visitors have to recreate their avatar at every visit?
No. The OptiDress avatar is kept for 30 days on the store: returning visitors find their digital twin and try on right away.
Can I try OptiDress before choosing?
Yes: the Maison Léon demo store is freely accessible, and a personalised 20-minute demo is available with no commitment.
