When you finally find a bra that you love, one that fits perfectly and one that you are willing to invest your money in, the question then becomes, how long should my new bra last?

In general, a good quality bra that is well taken care of and in rotation with 2-3 other bras, should last about one year. Having said that, the lifespan of any bra can be determined by several different factors.

Handwashing vs. Machine Washing
Machine washing a bra shortens its lifespan, period.
Even in a front-loading washer, even on the delicate cycle and in a mesh bag, and even if you don’t put it in the dryer, it’s the agitation that will break down the fibres of a bra and cause it to deteriorate faster. Hand-wash your bra every second or third wear with a gentle soap (such as Eucalan or Forever New) and lay flat or hang to dry.

Putting your bra on
Try not to flip your cups while getting into your bra or pull on any delicate lace, this can tear your fabric and cause your wires to poke out or snap.

Rotate your bras
Try not to wear any bra two days in a row. Rotating your bras will allow the elastic in the band to relax naturally and prolong the lifespan of your bra, keeping you on that first set of hooks longer.

A high quality bra versus a cheaper one will definitely maintain its integrity longer, but even with excellent care, like anything else, your bra will need to be replaced each year.
Since a good quality, well fit bra can completely change your posture and aid in your overall comfort, think of it as an investment in your health!
