HOW TO MEASURE

Two measurements. One minute.

1
Hips Stand naturally. Wrap a soft measuring tape around the fullest part of your hips and bottom. Keep it level and snug — not tight.
2
Waist (optional) Measure around the narrowest part of your waist, usually just above the belly button. Use this as a secondary check if you're between hip sizes.
