Fit Tips for 34AA
AA cups can be hard to find in stores. Look for brands specializing in petite sizing like The Little Bra Company.
If your 34AA 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.
