Your bra should fit snugly around you. You should be able to fit one or two fingers under the band comfortably. If you are pulling down on the back of the band or pulling up on the shoulder straps, then the band is too big.

If the shoulder straps dig in, try loosening the straps or try a strap with a larger width. One finger should run smoothly under the strap. Some bras have padded or gel cushioned straps.

Your breast should completely fill the cup. If there is gapping or wrinkling in the cup but the band feels fine, then go down a cup size.

You do not want to be spilling out of the cup from the top, bottom or sides. If the band feels fine, then go up a cup size. If you raise your arms, your bra should stay in place, snug against your body. It should not lift up or off. If this happens, loosen the shoulder straps and pay attention to how the band feels. If both of those are fine and your bra still lifts, go up a cup size.

Try on several different styles of bras. Every style fits and feels different and can shape your breast differently. Be sure and go shopping when you have some time and you are feeling well. Don’t rush it. When your bra fits correctly, it should not be painful or uncomfortable to wear.
