HOW TO MEASURE

MEASURE ONCE. MOVE WITH CONFIDENCE.

Use a soft tape measure over light clothing or underwear. Keep the tape level and comfortably close to the body without pulling it tight.

  1. 01
    Full Bust

    Measure around the fullest part of your bust, keeping the tape level across your back.

  2. 02
    Underbust

    Measure directly beneath your bust where the bra underband sits.

  3. 03
    Waist

    Measure around your natural waist, usually the narrowest point of your torso.

  4. 04
    Hip

    Measure around the fullest part of your hips and seat with feet together.

  5. 05
    Crotch-to-Heel

    Standing barefoot, measure down the inside leg from the crotch to the bottom of the heel.
