Fit Tips for 38C
C cups work well in most bra styles. If you experience spillover in one brand but not another, cup shapes vary — try different styles.
If your 38C 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.
