About this chart

  • Taken from Lacoste's interactive guide, category by category (52 combinations of gender, category and type). Unisex polo shirts, T-shirts, sweatshirts and jumpers follow the men's underwear chart (XXS to 3XL), unisex shirts the men's shirt chart (37 to 43). Kids' socks only come in one size.

Men

Polo shirts, T-shirts, sweatshirts and jumpers

Lacoste numbers its men's sizes: 2 = XS, 3 = S, 4 = M, 5 = L, 6 = XL, 7 = 2XL, up to 11 = 2XG. 1XG and 2XG are the big sizes beyond 4XL. The same chart applies to polo shirts, T-shirts, sweatshirts and jumpers. From 3XL, the brand gives a single value instead of a range.
