Fit Tips for 28G
G cups require well-engineered bras. Look for brands like Panache, Elomi, or Freya that specialize in fuller bust support.
If your 28G 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.
