Understanding This Size Chart

Women's Sizing: If you typically wear UK 6-8, try XS. UK 10-12 works well in S. UK 12-14 suits M, and so on.

Men's Sizing: We've provided suggested chest measurements to help you find your size. Measure around the fullest part of your chest, then match it to the guide.

Chest: This is measured flat from armpit to armpit (pit-to-pit).

Length (NP to HEM): This is the length from the nape (back of neck) down to the bottom hem.

Sleeve Length (SP to CUFF): Measured from the shoulder point to the cuff edge.

Still unsure? Measure an overshirt you love flat on a table, compare the measurements to ours, and you'll find your perfect fit. Or just drop us an email and our team will help :)
