How Often Should You Replace Your Bras?
There is no fixed expiry date, but there are clear signals. Here is how to tell when a bra has stopped supporting you, and why it happens.
People hang on to bras far longer than they should, usually because the bra still looks fine. But support comes from elastic, and elastic wears out invisibly.
A reasonable lifespan for a regularly worn bra is somewhere between six months and a year, though good care can stretch that and heavy wear can shorten it.
Why bras wear out
Every wear stretches the band and straps; every wash and dry cycle ages the elastic; body heat and sweat break it down further.
The fabric of the cups holds up much longer than the elastic that does the supporting, which is why a bra can look almost new while having lost most of its function.
Signs it is time
- You are on the tightest hook to feel secure. The band has stretched out. The tighter hooks were the bra's reserve, and you have used them up.
- The band rides up even on the last hook, or you can pull it far from your back.
- The straps will not stay tight, no matter how often you adjust them.
- The cups have lost their shape, wrinkle when worn, or the molded foam has creased or "broken."
- The underwire pokes through, twists, or feels bent.
- It simply is not comfortable anymore, even though it once was.
Sports bras wear out faster
High-impact sports bras take more stress and more washing, so they age quicker — often within six months to a year of regular use.
When the bounce control noticeably drops, replace it, because a worn sports bra is no longer doing the one job it exists for. See how to choose a sports bra.
How to make them last longer
Two habits extend a bra's life more than anything else: rotating several bras instead of wearing one into the ground, and keeping them out of the dryer. Both come down to protecting the elastic.

Re-measure when you re-buy
Replacing bras is also the perfect moment to re-check your size. Bodies change with weight, age, pregnancy, and time, and the size you bought two years ago may not be the size you need now.
