Here’s How Often You Really Need to Wash Your Bras

Let’s be honest: Laundry isn’t anyone’s favorite chore, and bras tend to be the unsung heroes of our wardrobe worn regularly, but often forgotten when it’s time to toss items in the wash. But if your go-to bra hasn’t seen the inside of a laundry basket in weeks, it’s time for a refresh. According to fabric care experts and dermatologists, you should be washing your bras more often than you think.

Not only does a clean bra help protect your skin, but it also extends the lifespan of your undergarments. Here's how often to wash your bras, why it matters, and how to keep them in great shape without ruining their delicate structure.

How often should you wash your bras?

According to Wendy Saladyga, fabric care expert and technical performance manager at Henkel, bras should be washed after every two to four wears. Sports bras, on the other hand, should be washed after every single use due to the sweat and bacteria buildup from workouts.

Even if your bra doesn’t look dirty, that doesn’t mean it’s clean. “Your skin’s natural oils begin transferring onto the fabric as soon as you put it on,” explains Maeve Gesualdi, bra specialist at size-inclusive lingerie brand Glamorise. This residue can create an ideal breeding ground for bacteria, potentially leading to skin irritation or breakouts.

That’s particularly important for those with sensitive skin, notes Lindsey Zubritsky, MD, FAAD, a board-certified dermatologist. “For people who already have skin conditions like eczema or psoriasis, this can lead to flare-ups or discomfort,” she says.

Why regular washing matters

Washing your bras regularly isn’t just good for your skin it also helps preserve the elasticity and structure of your bras. Sweat, oils, and environmental dirt can degrade the fabric over time, breaking down support and causing them to stretch out more quickly.

Tips for washing your bras correctly

You don’t have to hand-wash every bra in your drawer, but a little extra care goes a long way. Here’s how to make your bras last longer while keeping them fresh and clean:

• Use a gentle detergent: Look for dye- and fragrance-free formulas, especially if you have sensitive skin. “Undergarments are in constant contact with your skin, so this step helps prevent irritation,” says Dr. Zubritsky.

• Hook bras before washing: This prevents snagging on other garments and helps the bra keep its shape.

• Use a mesh lingerie bag: This protects delicate fabrics from damage in the wash.

• Select the delicate cycle: Cold water and a gentle spin help preserve elasticity.

• Always air-dry: “Never put bras in the dryer,” Gesualdi warns. “Heat ruins the structure and shortens their lifespan.” Instead, lay them flat or hang them to dry.

And yes, you can wash your bras after every wear if you prefer just be sure you're handling them with care. There’s no such thing as overwashing when you're doing it right, Gesualdi adds.

When to replace your bra

Even the most beloved bra has an expiration date. Over time, the elastic stretches, the cups lose their shape, and the band may feel loose especially if you’re already on the tightest hook and still not getting the support you need. These are signs it’s time to replace it.

“Your bra should fit comfortably without riding up or digging in, and it should support you without feeling restrictive,” Gesualdi says.

Best fabrics for sensitive skin

If you’re prone to skin irritation, consider the material of your bras just as much as their fit. “Synthetic materials like nylon, spandex, and polyester can trap heat and moisture, which can worsen skin conditions,” Dr. Zubritsky explains.

Her recommendation? Look for bras made from natural, breathable fabrics like cotton. Cotton is soft, non-irritating, and wicks moisture away from the skin making it ideal for everyday wear, especially in warmer weather.

And if underwires are a source of discomfort, opt for a wireless bra with gentle compression and a snug (not tight) band. The right bra won’t just support you physically it’ll protect your skin, too.

Taking the time to care for your bras isn’t just about preserving delicate fabric. It’s an act of self-care that supports your comfort, confidence, and long-term skin health.
