River Island size guide

Official chart in centimetres: women, men, kids, and baby.

About this chart

A British guide: the reference size is the UK size, and the French, Italian and US equivalents are those published by River Island. Only centimetres are reproduced. For women, two charts coexist: swimwear, skirts and shorts on one side, tops, dresses and jeans on the other, 1 to 4 cm apart for the same size.
