Step 1. Determine Your Underbust Size
Ideally have someone else take these measurements for you. Stand with your arms resting by your side. Measure around the body directly under the bust, ensure the tape is straight all the way around, and firm but comfortable. It is best to take this measurement while you are not wearing a bra, or you can wear a strapless, non padded bra-just be careful not to sit the tape over the bra or underwire. This measurement is your UNDERBUST.
