How to measure

Step 1

Firstly, you'll need to gather your measurements. If you don't have a measuring tape handy, you can use a piece of string, a scarf, or even a long article of clothing to wrap around your chest.

Step 2

You'll be taking two measurements: the circumference around your rib cage determines your band size (underband), while the measurement around your bust will help us determine your cup size (overbust).

Step 3

Your cup size is calculated by the difference between your band and bust measurements. After obtaining these measurements, please refer to the bra calculator or bra size charts provided with each product to determine your cup size.
