It comes down to personal preference, but the type of bra you wear, your exercise preferences, and how often you work out will all affect the longevity of your sports bra.
Rotating your bras is a clever way of extending their lifeline, but if you exercise every day, you’ll need to replace them more often.
Signs of wear and tear or a loss in elasticity indicate that your bra is on its last legs. A once snug and reliable sports bra that now allows excess movement indicates a lack of support. Adjustable bras may last slightly longer because you can tighten them, but it’s worth noting that this signals a change to your breasts or that your bra is reaching its sell-by. Check your cups for loss of shape, as this also means it’s time to reinvest.
As you age, your body will go through natural periods of change, including hormonal shifts and weight fluctuations, so make sure you regularly update your bra as and when you need to. If unsure, many outlets will measure for you and recommend a bra specific to the brand you’re shopping for.
