Fit Tips for 38D
D cups benefit from wider straps for comfort. Unlined bras can provide a more natural shape at this size.
If your 38D 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.
