How to measure
1. Stand in front of a mirror wearing your best fitting bra, you will need a fabric measuring tape or if you do not have one you can use a string and a regular measuring tape to measure your markings on the string.
2. Measure around your body (in inches) underneath your bust where your breasts meet your body. The tape should be snug (but not cutting in), parallel to the floor and you should not hold your breath. This is your BAND size - if you measure an uneven number, round up.
3. Measure around the fullest part of your bust, again making sure the tape is level around your body and not so tight to cut into your breast tissue. The difference between this measurement and your band size will determine your cup size. For every inch difference you will go up a cup size.
I.e. Your band measurement is 34, your bust measurement is 39 = 34E
Your band measurement is 35, your bust measurement is 39 = 36C
