How long are bras supposed to last?

Bras are supposed to last for six to twelve months. Over time, bras lose elasticity and shape, making them less effective. The length of a bra's life depends on how frequently you wear them and how well you care for them. Putting bras in the dryer, wearing bras that are too small, and wearing the same bra every day will speed up the rate at which bras need to be replaced.
