Your Bonds Bra Size

Your overall bra size is a combo of the underbust and bust measurements, follow the steps to find your measurements and use the sizing table for the recommended Bonds fit.
It really is as simple as 1 + 2 = 3.

1. Your Underbust Size

Wrap a soft measuring tape around your back & under the bust. Ensure it’s not too tight or loose and the tape is evenly level to the ground. If you’re measuring in a half cm, round down to the nearest whole cm.

2. Your Bust Size

Same process, but this time wrap the tape across the fullest part of your breasts & your back. The tape should sit firm but not squeeze. If you’re measuring in a half cm, round up to the nearest whole cm.

3. Your Bonds Bra Size

Match the cm measurement of your band/underbust (numbers going across) and bust (column going down) on the sizing table. The result is the recommended size for your next Bonds Bra.

For example, if your underbust is 73cm and your bust measurement is 93cm, the recommended size for your next Bonds Bra is 12C.
