How to Measure

Chest: measure around the fullest part of your chest, just under your arms, keeping the tape level.
Waist: measure around your natural waistline, where you usually wear your trousers.
Hips: measure around the widest part of your hips and seat.
Foot length: stand on a sheet of paper, mark your heel and your longest toe, and measure between the marks. Measure your larger foot.

Fit Advice

Between two sizes? Choose the larger size for a relaxed fit, or the smaller one for a closer fit.
Want to wear a jumper or hoodie under a jacket or coat? We suggest going one size up.
For shoes, we generally recommend the larger size when you are in between.
