My bra rubs underneath my armpits does this mean its too small or to big?

If your bra rubs underneath your armpits, it is likely that it is too small. This is because the underwire or band of the bra is digging into your skin, causing irritation and discomfort. When a bra is too small, it can also put pressure on the breast tissue, leading to pain and discomfort.

To determine if your bra is too small, you can measure your band and cup size. If the band size is too small, the bra will be too tight and will dig into your skin. If the cup size is too small, your breasts will not be fully contained in the bra and may spill out over the top or sides.

If your bra is rubbing underneath your armpits, it is important to get a new bra that fits properly. This will help to relieve pain and discomfort and can also prevent further damage to the breast tissue.
