Your measurements may show that you fit into more than one size. You will need to choose based on the preferred level of compression you like. If your hip and waist measurements put you in conflicting sizes, prioritize hip measurement over waist. We also recommend you consider the level of stretch of fabric in the style you are selecting as often if you technically can fit in more than one size, the smaller may work better in high stretch and the larger may work better in a low stretch fabric. 

A) BUST- Measure around the fullest part of the bust
