Is cotton underwear really better?

Unlike synthetic materials, which may cause excessive sweating and less air circulation, "Cotton underwear provides breathability, keeping you cool and dry," says Ra’el Cohen, co-founder and chief creative officer of ThirdLove. This is beneficial, since "the water-wicking fabric reduces the likelihood of moisture-related issues such as rashes and discomfort." Synthetic materials can also cause mild irritation on the skin (especially on a hot day), but Cohen adds that cotton is suitable for individuals seeking comfort or looking to reduce their risk of discomfort and chafing.

In terms of vaginal health, cotton underwear for women is also the superior option if you want to avoid yeast infections, explains Jessica Shepherd, MD, ob-gyn at the University of Illinois at Chicago and chief medical officer at Verywell Health. "Yeast infections are more likely to be caused by wearing underwear made from synthetic materials. Therefore, cotton is very helpful in minimizing your risk."

Should women wear 100% cotton underwear?

"Your cotton underwear should be made of at least 90 percent cotton," says Deepa Ryan, Founder of Peachez. "Some underwear may also have 10 percent elastane to give them a stretchy finish." Although cotton is known for its comfort and breathability, Ryan understands that it may not be your first choice in the aesthetics realm (hi, satin and silk). "In any case, be sure that the gussets of all your underwear are made of cotton to allow for moisture absorption, no matter the fabric of the underwear itself," she advises.

All the picks stem from editors, reviewers, gynecologists, and undergarment experts. Shop brands like Skims, Parade, Aerie, and Amazon, below.

Cotton Stretch swimsuit Panty

While you may know Calvin Klein for its famous bralettes, the brand's underwear is equally as cozy. Case in point: this super soft Cotton Stretch swimsuit panty. Made with cotton and elastane, it's cozy enough to wear all day without slacking on shape retention.

It was designed with the signature CK logo on the waistband, which was made to stay in place while remaining flexible. Plus, it's super easy to clean since it's machine-washable. If black isn't your thing, you can opt for the light gray version to mix things up.

I own two pairs of this underwear, and I love how, even after weekly use, it never stretches out. Every time I put it on, it feels just as stretchy and smoothing as it did the first time I wore them. While I love to lounge in it, I also recommend it for the gym as it contours my hips and tummy under my leggings.

Rave Review: "It is so comfy. The waistband feels great—no digging in. The underwear is soft and stretchy and the fit is perfect."

Cotton Thong Panties

These low-rise thongs are made with a super breathable, seamless fabric that moves with you, so they're great for the gym. Each order comes with a pack of six. And while you can invest in this color set, you can also buy it in all black, pastels, white, neon, stripes, and more.

Reviewers also love that it has enough material to provide coverage without bunching up in the crotch area. One even says she wears this underwear and nothing else because of its softness.

Rave Review: "I wear this practically everyday. I bought a bunch more pairs through a friend’s account and I’m obsessed. They fit as advertised and they're soft."

The Thong English Rose

Women's Health contributor Naydeline Mejia loves this elegant cotton underwear. "I love Cou Cou Intimates' panties because it's breathable, super comfortable, and very chic. The French lace detailing is a welcome addition!"

Although it has lace, this cute thong is seamless enough to wear under a slip dress or lightweight skirt, so you don't have to worry about any unwanted panty lines. You can also buy a matching top to pair it with.

As far as sizing goes, you can rest easy knowing it's true to size. However, if you think you may be in between sizes, the brand recommends sizing up just in case. You can also use the sizing chart on its website for more insight.

Rave Review: "The best thongs I’ve ever purchased. So lightweight and comfortable. Definitely buying this in white."

Superchill Cotton Cozy Lace Boybrief Underwear

This Aerie Boyfriend is known for being suuuper soft. An added perk: It stays put and doesn't ride up in the back (which, if you've ever worn briefs, is hard to come by). If this deep, forest green isn't your style, you can choose from six other earth-toned colors to match your vibe.

Unsurprisingly, one tester says this style is her all-time favorite because the lace is so soft and doesn't leave imprints on her skin. Other users like how much coverage this style provides, with one person noting that it's perfect for sleeping. Still, some reviewers note that it runs a little bit big.

Rave Review: "It is super flattering and has a comfortable feel to them. Not only are they cute, but the color is magnificent. So happy with my purchase!"

Cotton Underwear Briefs

This high-waisted underwear is perfect underneath a tight dress when you don't want to put on shapewear, but you still want to smooth out your curves. According to the brand, you can't see any panty lines when you wear this brief. The added tummy support is also a plus, and, according to reviewers, the waistband doesn't roll down or bunch either.

Another perk: It runs from a size small all the way up to 5X, so a wide range of body types are accommodated for. Testers note that this brief is especially comfortable for those who are postpartum. Others say that it provides just the right amount of compression while remaining breathable.

Rave Review: "I only do reviews for things that actually solve the problem I bought it for. These panties are perfect under clingy summer dresses. I mean zero indention line at the waist/hip."

The Cotton Thong

Everlane's cotton underwear shows no lines through your clothing, which is why reviewers love wearing it to the gym and out on the town. It features a super soft fabric alongside a tagless design and ultra-smooth waistband, so you can trust it to stay out of sight and out of mind all day.

Testers rave about how breathable and comfortable it is. They also note that this thong is extremely durable. One person even says it feels like a "second skin."

Rave Review: "I still have to get used to wearing a thong, but the fit is great and the fabric is so comfy. It doesn't pinch my skin like other panties!"

The Roxanne Brief

Turn your underwear game up a notch (or two) with these hot briefs from Peachez. The back is slightly see-through for a bit of flare, and the front features a gorgeous scallop lace design and double string holds on both sides.

Another fun fact: the Roxanne Brief is sustainably made using 100 percent recycled lace. As far as cleaning goes, just know that the brand states these shouldn't be washed in water warmer than 40 degrees. Specific? Yes. Worth it? Also, yes.

This isn't the only style that Peachez offers. The brand also has a subscription service, so you can opt in to receive a surprise package of brand new underwear at your doorstep every month. Sounds convenient, right?

Rave Review: There are no reviews for this product yet, but Ryan says to look for underwear that are made with at least 90 percent cotton. This pair outdoes that recommendation, as it's made with 100 percent organic cotton.

Cotton Breathable Panties

If you ask anyone how they feel about thongs, someone is bound to mention the constricting feel of them—totally understandable. However, these breathable panties from Elacucos will do just the opposite.

The high-quality cotton in the fabric makes this thong uber comfy, and it doesn't get stuck in any unwanted areas (IYKYK). If you're worried about it being too tight, you can safely size up without worrying it'll be too baggy.

Need more convincing? Testers agree that this is breathable and soft. Additionally, they note that while the material is stretchy, it doesn't loosen over time. Many users say you don't see it through your clothes, making it great to wear anytime, anywhere.

Rave Review: "This is my go-to underwear. It has the perfect amount of stretch, doesn't show lines, and feels like you're wearing nothing!"

Organic Cloud Cotton Hipster

According to Cohen, this pair of underwear is created with a unique blend of organic cotton fibers that are naturally soft and breathable. "This ensures lasting comfort throughout the day." In true Thirdlove form, its irritation-free fabric is comforting on sensitive skin.

If you hate the feeling of underwear waistbands digging into your skin, just know this one doesn't have bulky plastic elastic bindings. The fit is true-to-size, and they provide the right amount of moderate coverage. Just throw them in the wash with a lingerie bag to maintain the quality.

Rave Review: "I was looking for a 100 percent cotton panty and am happy with these. They are breathable and stay up, and come in cute colors. Would purchase again."

Cotton Rib Boxers

Sometimes, underwear doesn't feel protective enough, but this rib boxer from Skims is the perfect stand-in. Super high-waisted, it holds in your tummy when you feel extra bloated if you want that smooth appearance.

During your time of the month, it's a great option for sleeping shorts. Pro tip: Put your pad in the gusset of this short if you want it to stay in place all night. It's time to finally put your worries about leakage to rest.

Testers are head over heels with this boxer. One user says it's breathable enough to serve as the "perfect sleepwear." Others rave about how versatile it is. Some even double the boxer as loungewear for days at home because of how chic it looks.

Rave Review: "This really is such nice fitting underwear. It's comfortable and almost feels like you’re not wearing anything."

G-String Thong

If you're anything like me, you love a G-string thong because it's basically invisible. This pair (which comes in a pack of 10!) is exactly that and more. Made with a double layer of cotton for added protection, this panty is full-coverage in the crotch area without slacking on breathability.

The super stretchy waistband doesn't feel constricting, and users love that it has a low-rise design to pair with jeans, yoga pants, leggings, and more. As far as item care instructions go, you can put this in the washing machine or scrub it by hand. The brand also suggests tossing each pair after three months of use, so be prepared to restock!

Rave Review: "This is the most comfortable thong EVER. I feel like I have nothing on when I wear it"

Everyday Classic Fit swimsuit

Everyone has a pair of underwear they wish they could wear every single day, and this provides comfort that no other undies can quite match. Besides its snug fit and super cozy fabric, it's sustainable, so you can feel extra good while wearing it.

BTW, testers say this swimsuit feels almost like a second skin because of how smooth it is. They agree that it runs true-to-size, so no need to stray from what you usually order. Users also love the soft waistband and how gentle it is on their skin. Convinced yet?

Rave Review: "I literally wear it out then shop for more. Always a great feel and I enjoy shopping while doing something good for the environment."

Breathable swimsuit Panty

It's important to take extra care down there, especially if you sweat a lot. That's why you can't go wrong with a moisture-wicking, breathable panty. This pair in particular has a double layer crotch, which provides that cool, dry, and comfortable feeling you wish all your undies had.

Testers are obsessed with this, noting that the quality feels brand new even after a year of owning it. The budget-friendly price is also something that several users appreciate.

Rave Review: "I bought this pack because I like the bikini-cut style in underwear, and you can never go wrong with the color black. It feels nice and comfortable, and it doesn't ride up."

Rave Reviews: "It has a great quality and has great stretch. If you have curves and a butt, this is what you want!"

Vintage String Cheeky

You may have heard of a string thong, but have you ever tried a string cheeky? One of Parade's bestsellers, this pair of underwear is made from the brand's upcycled cotton blend and provides barely-there string coverage without feeling flimsy. It's totally invisible under leggings or tight dresses, so you can rest assured knowing your panty lines are well hidden.

It's also a great option if you're open to adding a pop of color into your dresser. This fun bright pink shade can be paired perfectly with a similar bralette. Additionally, you can get extra creative and mix and match with different colors.

Rave Review: "It’s super soft to the touch and I’m excited to wear it. The extra inclusion of stickers and a bandana in my package was awesome to find, too."

Rave Review: "Love these! Anything to make me more comfortable at 33 weeks pregnant is a must and these bad boys are fabulous. 10 out of 10 would recommend!"

swimsuit Reusable Period Underwear

It's made with a soft, stretchy fabric that hugs your hips without feeling constricting. This underwear also absorbs up to three tampons-worth of blood, so you can finally enjoy your day without worrying about bleeding through.

How our team chose the best cotton underwear for women

For the past year, Women’s Health associate e-commerce editor Lily Wohlner has been researching the bestselling, most popular, and top-rated cotton underwear for women. Our team consulted three experts for the story and filtered through hundreds of customer reviews to determine the best cotton underwear for a wide range of preferences.

How to choose the best cotton underwear

With a wide range of cotton underwear on the market, you might be wondering what makes a pair worth the investment. Here are a few things to keep in mind before you shop:

Materials: While cotton is known for its breathability, it's also okay to buy a pair that has some sort of blend of materials. "100% cotton is great, but cotton with a little bit of spandex will fit better and keep its shape," says Cohen. "The mix is sublimely stretchy, soft, and sustainable."

"Tencel is another fiber that can be mixed with cotton for a super soft feeling," says Kristen Saladino, Women's Health executive fashion director. "Plus, it’s good for the environment."

Sizing: Cohen notes that you should also figure out what style you'd like to wear. "Undies can be thongs, swimsuits, hipsters, and briefs so you can get as little or as much coverage as you'd like," says Cohen. "Once you've found your style, the size you typically wear should be fine."

Still, if the fit is a concern, Saladino suggests looking at the customer reviews to see if the fit tends to run large or small, in addition to viewing the company's sizing chart if it's available.

Colors: The color of the underwear you select mostly comes down to what your style is. However, it's also worth keeping in mind that darker colors contain more dye, which could "come off and irritate sensitive skin," says Cohen. Her advice? Opt for organic cotton since the dyes aren't as harsh, and wash newly bought underwear.

Care instructions: Many underwear brands suggest hand-washing your underwear to preserve the quality. But if you're used to relying on the washer and dryer, no worries! "You want to be able to wash and dry your underwear and not think about it," says Cohen. "Cotton will last longer than synthetic fabric in the washer and dryer." For extra protection you can also use a lingerie bag in the wash, adds Saladino.
