How to measure

Use a soft tape measure and, if possible, wear an unpadded bra. Keep the tape parallel to the floor and take each measurement in front of a mirror to check it is level at the back.

1. Underband. Measure directly under your bust, where the band sits. Pull the tape snug but not tight, and breathe out before reading the number.
2. Bust. Measure around the fullest part of your bust, standing straight with arms relaxed at your sides. Keep the tape loose enough to slide a finger underneath.
3. Find your cup. Subtract the underband measurement from the bust measurement. About 1 in is an A cup, 2 in a B, 3 in a C.
4. Between sizes? If your underband falls between two numbers, take the smaller band and go up a cup — for example 34C rather than 36B.
