Size recommendation

The size, from the garment size chart.

SizeFlow recommends the size from height, weight, age and gender: it works out body measurements and compares them with those of the garment on the page.

01How it works

From details to size, in four steps.

The widget opens from the product page with “Get your ideal size”. At the end, the recommended size stays on the page, next to the garment's sizes.

Height, weight, age and gender Body shape Body measurements Recommended size 38, slim fit

You decide how it should fit.

A slim blazer and an oversized puffer are not chosen the same way. With your product team we set how each line should fit.
