How does US to UK sizing work?
For women's clothing, UK sizes are exactly 4 higher than US sizes — US 6 = UK 10, US 8 = UK 12. This rule applies reliably across tops, dresses and bottoms.
For men's clothing, US and UK sizes are generally the same when expressed as labels (S, M, L) or chest inches. Differences arise with EU sizing which uses centimetres.
For women's shoes, subtract 2.5 from your US size to get UK. For men's shoes, subtract 0.5.
