How to measure — body measurement diagram

How to measure

Bust / Chest

Measure around the fullest part, keeping the tape level and under the arms.

Waist

Measure around the narrowest part of your natural waistline.

Hip

Measure around the fullest part of your hips and seat.

Inseam

For bottoms, measure the inner leg from the top of the thigh to the ankle.

Measure over light clothing, keep the tape snug but not tight, and if you're between two sizes we'd suggest sizing up.
