How to Measure
Chest
Wrap a soft tape measure around the fullest part of your chest, keeping it parallel to the floor. Don't pull it tight — breathe normally.
Band
Measure snugly around your ribcage, directly under your bust. Round to the nearest inch.
Waist
Measure around your natural waist — the narrowest part of your torso, usually about an inch above your belly button.
Hip
Stand with feet together and measure around the fullest part of your hips and seat, keeping the tape level.
When in doubt, size up. All SMRc apparel is designed to move with you — a little extra room never hurt a PR.
