A few tips for picking out the right bra - Trouble shooting fitting tips
Do you bulge over the top or out the sides of your bra?

When bulging occurs, the cup does not have enough capacity to contain all of the bust tissue; and the simple remedy is to choose a larger cup size. Either take a measurement or check the size of the bra currently worn and proceed. If other problems have caused you to increase band size and your customer needs only slightly more cup capacity, first try a larger band in the same size.

Remember: 36B has slightly more cup than a 34B.
