Enter your measurements

Measure underbust and overbust with a soft tape measure (worn bra off or thin top), then tap Calculate My Size.

How to Measure Correctly

Underbust: Wrap a soft measuring tape snugly directly below your bust, parallel to the floor. Breathe normally. Do not pull tightly. Round to the nearest inch or cm.
Overbust (bust): Measure around the fullest part of your chest at nipple level, parallel to the floor. Do not compress the breast tissue. Lean slightly forward for accuracy.
Tip: Measure without a bra or wearing only a thin unpadded bra. Avoid measuring over a padded or push-up bra.
