Measurement 1 - Body Size
Using a soft tape measure, measure your high chest under your armpits and around your back. Keep the tape measure parallel all the way around. Do not pull too tightly.

 Measurement 2 - Cup Size  
Wearing an unpadded bra, measure one breast at a time starting at the outside edge of the underwire (at the breast bone), and end at the outside edge of the underwire near the underarm. If one breast is larger, use the largest of the 2 numbers as your cup size. Note, if you are measuring in a minimizer bra, add one inch to the cup size measurement.

Why is the Unbelievabra sizing different then a regular bra?
Because the Unbelievabra has no bands or closures, the old fashioned way of bra measuring may not give you your precise Unbelievabra size. With our measuring guidelines (see instructions on left), you will be sure you are ordering the size that will fit you best in the body and the bra cup.

Don't be surprised if you measure larger or smaller than you thought you were. We want you in the correct size so you look and feel your best in your Unbelievabra.
