HerRoom Response: When a wire snaps in the middle, it usually means there is too much strain pulling the underwires apart. This can be because your band size is too small, or you cup size is too small. If the cups are fitting you, I would first try going up a band size and down a cup size to maintain the same cup volume. In your case, it sounds more like you have the wrong band size. If your underwires also snapped at a 40 band size, try going up to a 42 and down one or two cup sizes.

HerRoom Response: IF you feel there is not enough support for the bottom of your breasts, it could be that your band size is too large. Consider going down a band size and up a cup size to maintain the same cup volume - in your case, a 42D.
