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.
"The 'rule' is that a bra should be washed after every wear, since it's directly in contact with the body," laundry expert Mary Marlowe Leverette told PureWow. "Body oils, perspiration, and bacteria are transferred to the fabric and if left in the fibers will begin to break down the fabric—especially elastic fibers."
"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."
To make your bras feel, function, and look their best for as long as possible, you need to properly care for them. Most bras should be washed after about four wears, or more frequently if you have a particularly sweaty day. Sports bras should be washed—or at least rinsed with warm water—after every workout.
"Our general rule: wash your bra for every three wears, assuming that you're wearing the bra only for 'normal' activity—that is, sitting at your desk as opposed to exercising," says Kunitomi.
A good rule of thumb is three everyday bras: Two in a neutral color or skin tone shade. At least one darker color, like Black, Espresso, or Olive, for outfit variety.
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.

A:There is no clear cut time limit for which a woman should wear a bra. It depends upon the size of the breasts, and the type of work one is doing. Main reason for wearing a bra is to give them support while working.
"On average, they own 16 at any one time, topping up their collection with four purchases each year." And then the story goes on to reveal that while we women have enough bras to go at least two weeks without doing laundry, on average we wash them only every two months.
The best way to protect your bras during a wash cycle is to place them inside a mesh laundry bag and wash using mild detergent and cool water on the delicate cycle setting, making sure to air dry afterwards. These precautions can help protect the bra's shape and structure, but it does not guarantee it.
Check the care label first, but many bras are machine washable. All you need is a lingerie bag! If placed in the machine freely, bras and undergarments with lace details and trims can start to fray and unravel due to friction against other garments in the wash.
In addition to the gentlest detergent, it's also important to use the gentlest cycle when machine washing delicates. Only use cold water since hot water can cause colors to bleed and can affect the shape of your bras.
The risk of getting an actual skin infection from a dirty bra—anything beyond pimples and some irritated, itchy skin—is really low, Waleed Javaid, M.D., director of infection prevention and control at Mount Sinai Downtown, tells SELF.
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.
There's lots of info floating around the interwebs debating whether or not it's safe to go braless during bedtime—but experts say there is absolutely no research to support claims that wearing a bra 24/7 is bad for you.
If you don't want to wear a bra, you and your breasts will be just fine—though if you notice back pain or soreness in your breasts, consider wearing a bralette or comfortable bra to offer at least a little support. And if wearing a bra gives you confidence, by all means, keep clasping one on every morning.
Bra—1 bra for every three days of wear. If you are planning on physical exercise, bring a sports bra for each day of sweat-inducing activity. As I shared in this article, figuring how often you need to wash a bra is not an exact science, as it requires a balance between convenience and cleanliness.
It could be down to hormonal changes
Throughout the day, you may find that they affect all manner of things. Often enough, an increase in hormones could mean that your breasts swell or start to feel larger. That is typically completely normal but it can play havoc with your lingerie.
Everyday bras
These are the bras that we reach for day after day. They go with most of our clothing, and we can rely on our everyday bras to keep us comfortable and supported all day long. But this everyday style doesn't have to be boring. A good rule of thumb is to have three everyday bras on rotation.
No matter the type of bra, the band should fit comfortably around your body, snug but not tight. Remember to always start a new bra on the loosest hook and hook tighter as the band stretches over time.
"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.
