Measuring band size

There are two ways to measure your band size. The best bet is to do it both ways to see if you get a consistent measurement.

1. Bring the measuring tape around your back to the front, keeping it under the arms and bringing it up across to the middle of your chest (see image). If you get an odd number, round up to the next even number to get your band size.

2. Measure across the bottom of your band, directly under the bust and across your ribcage. Make sure to keep your measuring tape straight around the back to front. Again, if you get an odd number, round up to the next even number to get your band size.

Measuring cup size

1. Measure loosely around the fullest part of your bust, with the tape straight across and around your back, bringing it to the front.

2. Subtract your band measurement (from step 1) from this bust measurement. The difference calculates your bra size- each inch represents a cup size. For example, if you measure a 34 inch band size, and a 36 inch cup size, the difference is 2: which would indicate a B cup.
