FitPerfect AI turns a few quick photos into a complete picture of how clothes will fit you. No more guessing between sizes, no more returns for the wrong fit — just confident shopping from any brand, in any fabric, anywhere.
Upload six or more photos of yourself from different angles. Your privacy is protected at every step — photos are stored privately, used only to calculate your sizing profile, and you can delete them anytime from Settings. The whole upload takes under two minutes and works right from your phone.
Our AI estimates your body measurements — height, bust or chest, waist, hips, inseam, shoulder width, and more — then maps them to exact garment sizes across every category. Your sizing profile factors in your preferred fit per brand, the fabric of each garment, and your location for regional sizing standards in the US, EU, UK, and Asia.
Dress your personal 3D AI body model in any outfit, slide the size up or down, and rotate it a full 360 degrees to judge the fit before you buy. Compare sizing side by side across brands and fabrics so you always know exactly what size to order from any retailer, the first time.
Save your favorite looks to a smart lookbook, log how past purchases fit so the AI gets smarter with every order, and export a printable shopping checklist whenever you are ready to buy. Membership is $4.99 a month with full access to every feature — cancel anytime, and keep your profile and lookbook even after canceling.
Returns and size swaps start with a single problem: you do not know your true measurements. FitPerfect AI solves that with a private body profile built from your photos, then maps it to exact sizes for every brand and fabric you shop.
