How to measure:
With a soft measuring tape and an unlined bra or thin tank top, start by measuring your under-bust, where your band will sit. Wrap the tape around your body, keeping it taut but not tight. Take a deep breath in and out to allow your rib cage to settle, take note of the measurement.
Then, grab your cross-cup measurement. Lay the measuring tape at the center of your chest, then measure across the fullest part of your breast, stopping where the breast tissue ends at your side.
With both measurements, see where the line up on our size chart, rounding up if you're between inches.
