H&M → Gap
Different brands. Different sizes. Different countries.
A Medium in H&M is not the same as a Medium in Gap — and your size changes again depending on whether you're shopping in the US, UK, EU, or Asia. WhatSize handles both.

Why H&M and Gap sizes don't match
There are no international standards for clothing sizes. H&M and Gap each define their own measurements for sizes like "Medium" or "Size 10."
It gets worse across regions. A H&M Medium in the US is a different measurement to a H&M Medium in Europe or Asia. Same brand, different country, different size.
WhatSize handles both — brand differences and regional differences — using the actual centimetre data.
