Fit Tips for 42DDD
DDD/F cups benefit from full-coverage styles and three-part cups that offer structure. Side support panels are helpful.
If your 42DDD 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.
