UK Size Guide for Women and Men

In the UK, women's clothing uses numbered sizes (6, 8, 10 and so on) and letter sizes (XS to 5XL), while men's clothing mostly uses letters matched to chest size in inches. An XL in the UK is usually a women's size 16 or a men's 42–44 inch chest. Use the tables below as a guide, then check the size chart on each product page, because fits differ between styles.

How to Choose Between Two Sizes

Measure a similar garment you own and compare it with the size chart rather than guessing. For relaxed knitwear and outerwear you will layer over other clothes, check the chest and length measurements carefully. Every order can be returned within 30 days if the fit is not right.
