How often you need to wash your bras isn't an exact science. But dermatologist Alok Vij, MD, says that as a general rule, you should wash them after every two to three wears.
About a third of women surveyed said they wash their bras every two weeks — but nearly half of the women surveyed wash them less often than that. (Sports bras are another story. Nearly all the women surveyed wash those after every workout, which seems like a good idea).
"By not washing bras frequently, body soils like sweat, sebum, and skin cells can build up on bras, which can eventually lead to malodors and even residues and dinginess," Wang warns. And, according to Miller, any bacteria left on the bra can lead to annoying skin problems, such as "irritation or rash."
Because bras are delicate items, you need to take special care while washing them. The best way to wash a bra is to wash it by hand using gentle detergent. If you don't have the time to hand wash your bras, you can machine wash them in a mesh lingerie bag on the delicate cycle with cold water.
All that, of course, depends on the duration of your trip, but we'd say three is a safe bet for a week-long getaway. If you're staying any longer, throw in an extra bra or two, or consider giving them a wash at the very least.
It's also important to rotate your bras, so the cups and straps can relax. This allows them to retain their shape and elasticity. “You can wear the same bra two days in a row, as long as you take it off for several hours in between to allow the bra to relax,” Dr. Vij says.
Unless you're regularly breaking into a sweat, you don't need to change your regular bra every day. A change twice a week (or at least once a week) is a good guideline to aim for. However, breaking into a sweat isn't the only thing that should prompt you to change bras.
As a general rule of thumb, it's important to have a healthy rotation of bras at the ready so that you're never left blindsided — and bare chested. All things considered, we'd suggest owning 11 bras in total in a couple of distinctive styles that range from everyday to on-occasion.
While it is correct not to overwash your bras, as it can damage the elasticity of the bra, which is crucial for proper support, Pour Moi's Lingerie Technologist, Lois Siciliano, advises washing them every two to three wears.
How Often You Should Wash Your Sheets (And How to Get Them Really Clean) Experts recommend washing or changing sheets once a week.
Most people have between one and four special occasion bras, though some may have more depending on their style and what type of clothes they like to wear. You might own anywhere between five and 15 (or even more) bras. It all depends on your lifestyle and your preferences.
Is it OK to sleep in my bra? There's nothing wrong with wearing a bra while you sleep if that's what you're comfortable with. Sleeping in a bra will not make a girl's breasts perkier or prevent them from getting saggy. And it will not stop breasts from growing or cause breast cancer.
Even with gentle usage and care, all bras will lose their shape over time as the elastic fibres in the band and straps begins to deteriorate. It's generally recommended that a bra should last anywhere between 6-9 months, although we think that with good care your bras should last a lot longer.
If the top of your bra cups curls outward, it probably means that the stitching in the bra has gotten stretched over time. If your bra cups are folding over or there are gaps between your breasts and the cups, it means your bra is worn out or you're wearing the wrong size.
Overuse will lead to detergent buildup, which in turn will lead to the development of a sort of mildew-y smell, because the soap combined with your sweat, oils, and dander creates a perfect environment for bacterial growth.
Most people wash their bras in the washing machine, but one bra expert has said this will "ruin" them and they won't last as long. Assistant Manager at lingerie store Bravissimo's, Mercie Smith, says one safe method of washing them is in the shower.
In fact, experts recommend replacing bras every six months—or after about 180 wears.
On average, you should own between 20 and 25 pairs of underwear. The amount of underwear you should have depends on how often you do laundry, your activity level, outfit choices, and personal preference. Having roughly 20 to 25 pairs ensures most people that they will never run out of underwear.
Since your everyday bras are the ones you're most likely to wear, well… every day… you'll want to have a few on rotation. A good rule of thumb is three everyday bras: Two in a neutral color or skin tone shade.

"If you don't wear a bra, your breasts will sag," says Dr. Ross. "If there's a lack of proper, long-term support, breast tissue will stretch and become saggy, regardless of breast size." Still, both experts agree that multiple factors play into if and when sagging (technical term: "ptosis") occurs, bra-wearing aside.
Shapiro, there are no known health risks associated with not wearing a bra. “There is no 'wrong' answer,” Dr. Shapiro says. “If you find that you're the kind of person who's comfortable and confident without a bra, that's fine.”
Many factors can play a part in your breast cancer risk, but going braless isn't one of them. The bottom line: "Generally speaking, wearing or not wearing a bra really won't have a significant impact on your overall health," Dr. Sahni said, adding that it's entirely a personal choice.
