Why are my bra cups gaping at the top?

Cup gaping is most often caused by cups that are too large or a cup shape that doesn't match your breast shape. Other causes include poor posture, not performing the scoop-and-swoop method, and worn-out bras. The fix depends on identifying the root cause.

Is cup gaping always a sign the cup is too big?

Not always. While cup gaping often means cups are too large, it can also happen when cups are too small — the lack of space pushes the bra outward, creating gaps. Bra style matters too: full-coverage cups on shallow breasts will gap even in the correct size.

How can I fix bra cup gaping?

Start by remeasuring with our calculator. Try one cup size smaller, switch to a demi or balconette style for a better shape match, and always use the scoop-and-swoop technique. If gaping persists, consider bras with stretch lace or flexible cup edges.
