HOW TO MEASURE.png__PID:39697daa-0f8f-4ef9-9cae-94c9060549d5

1. BUST

Wrap a soft measuring tape around the fullest part of your bust — usually across the nipple line.The tape should feel snug but not tight. No bra padding.

2. WAIST

Measure around the narrowest part of your waist — typically just above your belly button.Keep the tape flat and resting naturally on your skin. No need to hold your breath.

3. HIPS

Measure around the widest part of your hips and butt.Make sure the tape is level and not too loose or too tight.
