How to measure:

All measurements in the table are body measurements, not actual garment measurements. Breeches are sold according to waist measurements. Measure your waist at the narrowest point (A) and your hips at the widest point (B).

The inseam is the inside of your leg, and is measured from the crotch to the ankle (C).
