Fit Tips for 28A
A-cup bras often benefit from light padding for shape. Bralettes and triangle styles are popular and comfortable.
If your 28A bra is gapping at the top of the cup, the cup may be too large or the wrong shape — try a demi-cup or balconette. If the center gore doesn't sit flat, go up one cup size.
