Apparel sizing is StrutFit Size. Already running Find or Try? It uses the same install, so adding it is a switch, not a new project.
See pricingThe shopper answers a few quick questions: height, weight, and their body shape, shoulders and leg length. StrutFit estimates their body measurements from those answers - chest, waist, hips, shoulders, leg and arm length, thigh - and reads them against the cut of the garment they're looking at, calibrated on your own return data. They get one size, and how it will fit.
No. Everything comes from questions they can answer in a few seconds. Nobody is asked to measure themselves, and nobody needs to upload a photo.
Yes. Each garment is fitted to its own cut, so a relaxed shirt and a close-cut dress can give the same shopper different sizes. Leg length is one of the questions, which is what trousers and jeans need.
We publish measured return figures for footwear sizing, from HOKA, Pikolinos and Birchbury. We don't yet publish one for apparel, and we won't until we've measured it on a named customer's traffic. Every style is calibrated against your own return data before go-live.
No. Once a shopper has been sized on any StrutFit store, they arrive at yours already sized and are asked nothing at all.
