The best no-show underwear for a seamless look

"The Evelyn & Bobbie thong is my favorite to wear with high-rise leggings, because it feels like wearing not much at all. It's extremely breathable, the material is buttery soft, and it's absolutely invisible. The stretchy waistband has just the slightest bit of compression so it feels supportive, but never constricting.

I like that these give me more coverage than a G-string, but still have the practicality of a thong. You can get them in one of two sizes that stretch to fit a wide range." — Gabrielle Chase, associate style editor, Insider Reviews.

"Though Spanx may be best known for its shapewear, the brand is responsible for some of our favorite comfy lounge clothing — and now our daily underwear, too. I tend to be skeptical of one-size-fits-most underwear, but these actually deliver. Crafted from a breathable nylon-elastane material with a 100% cotton gusset, the thong stretches up to 400 percent to accommodate various body shapes and sizes (One Size is designed to fit sizes XS-XL, and One Size Plus covers sizes 1X-3X).

Still, I found the fit comfortable but not tight. The thong stayed hidden under a pair of leggings and the quick-dry fabric was appreciated during my workout." — Talia Ergas, freelance writer, Insider Reviews

In our review of Bombas women's underwear, we found that the brand made famous for its socks is also a major player in the intimates category. This nylon-elastane thong (in sizes XS-2X), which is perfect for wearing under leggings during a workout, was a standout. 

"They come with a grippy, textured detailing on the inside that's intended to keep the underwear from moving around when wearing under leggings or other activewear," writes Sally Kaplan, Executive Editor, Insider Reviews. "I personally didn't find that the textured detailing was particularly helpful, but I do like the silky feel of the underwear. If you feel more secure with high-waisted styles, I wouldn't recommend this pair — but if low-rise is your usual go-to, these are a comfortable option I'd definitely recommend."

True & Co. is known as the lingerie startup that surveyed 6 million people in search of the right fit for the best wireless bra. They've proven themselves capable of having best seamless women's underwear, too. Like their bras, panties come from a muted color palette and are seamless.

I like this True&Co. low-rise thong for its buttery soft and stretchy fabric comprised of nylon and elastane that feels like practically nothing on my skin. The raw-edge design doesn't have elastic or bulky seams, so it stays well hidden under my clothing, including light-colored leggings and silky skirts. It comes in XS-XL in 12 colors, including darker and lighter nude tones.

We love Negative Underwear's minimalist approach to luxury intimates with a focus on comfort, quality, and function. It's great for people who want high-quality lingerie without any (literal) frills, and it scored high marks when we had three staffers test a variety of the brand's offerings. 

This nylon-lycra high-rise thong is great for wearing under thin fabrics because the lightweight material is made with bonded seams that help conceal the panties. The sleek and stretchy style, which comes in black and buff in sizes XS-XXL, is basically invisible under clothing.

I own at least 10 pairs of ThirdLove's ComfortStretch Thong (in sizes XS-3X), and they're some of my favorite pair of panties for everyday wear. The nylon-Spandex fabric (with a 100% cotton gusset) has a ton of stretch, so I've been able to keep wearing the same size even through weight fluctuations. The fabric lays flat against my skin, and it's invisible under a tight pair of leggings or a figure-hugging sundress. I just wish they came in more colors, including darker nude shades.

When we tested Parade's underwear lineup, we were impressed with the brand's comfortable fit, breathable materials, cheerful color palette, and its use of recycled materials in its fabrics. This virtually invisible low-rise thong lives up to that same standard. It comes in 14 bright hues in sizes XS-3XL. The fabric is super smooth with a barely-there feel and vanishing edges.

Over the years, we've reviewed dozens of Everlane styles from shoes to denim, and we've consistently come away impressed with the brand's lineup of improved-upon basics. We also gave the label's ReNew Underwear — which includes minimalist, seamless styles made from 100% regenerated nylon — a test run, and we found it comfortable and flattering. 

If you're going for a no-show thong, we recommend the brand's aptly monikered Invisible Thong, which comes in five neutral shades in sizes XXS-XXL. "I was surprised by the Barely There Thong's high waist, but it ended up being my favorite aspect. It maintains the versatility of a thong's zero-panty-line effect while also delivering a relatively unique — and really flattering — high-waist silhouette. Plus, since the material is slightly compressive, it feels more secure. Aside from being seamless, they're also bonded, so they stay put throughout the day," writes freelancer Mara Leighton.

Kim Kardashian's intimates and loungewear brand stands out for its focus on inclusion. SKIMS' no-show nylon-Spandex thong, for instance, comes in eight different nude hues ranging from fair to dark and sizes XXS-4X. One reviewer called the mid-rise thong "extremely comfortable," adding, "You put them on and forget you are even wearing them."

If you're looking for a fitness-ready no-show thong, consider this style by Athleta. The nylon-Spandex fabric is quick-drying, moisture-wicking, breathable, and stretchy. One reviewer raved that it's "soft and firm" but "not flimsy" so you don't have to worry about it getting "overstretched." The thong comes in 10 neutral hues in sizes XXS-3X.

Reviewers love these "soft as butter" stretch Austrian modal fabric panties because they have a wide gussett, "so no frontal wedgie." If that's not enough to sway you into "going Commando," consider the flattering mid-rise cut with raw edges that remain completely hidden even when worn under leggings. The undies come in eight shades, including three different nude hues, in sizes XS through 3X.

If you're looking for a truly impressive color range on a pair of no-show undies, this high-rise thong from Hanky Panky stands out with 19 hues to choose from. (Unfortunately the size range is slightly more limited with only S-XL available.) People who have worn the moisture-wicking microfiber panties appreciate the comfortable, wide waistband and the "naked" feeling the lightweight, seamless fabric provides.

"I love that the Slip Short can be underwear, slip shorts, or pajama bottoms — they're whatever you need them for. They're incredibly soft, almost like stretchy silk. I wore mine under white shorts to test just how 'no-show' they could be, and was thoroughly impressed.

The legs were a bit long so I pulled them up a bit to conceal the hems, and they stayed right where I wanted them to without falling back down. The high rise waistband can also be adjusted to your comfort level. I love them so much that I'm looking forward to them being restocked in black." — Gabrielle Chase, associate style editor, Insider Reviews.

Wacoal's Body Base line offers lightweight and smoothing panties that won't be visible underneath your clothing. The stretch fabric is a combination of Spandex and nylon (with a 100% cotton gusset), which gently hugs the body and stays in place without squeezing. One user reported the brief "feels like a second skin" with a light amount of compression that "fits like a dream."

Though you may assume liquid-absorbing undies create bulk, Knix actually devised a super thin nylon-Spandex pair which is virtually invisible under clothing. There's a 9-inch built-in liner, which can absorb as much menstrual blood as two regular pads or four super tampons. The machine-washable fabric clings to your curves to prevent leaks.

These are comfortable even if you aren't on your period, because they also effectively absorb sweat. They come in 13 colors (including five nude shades) in sizes XS-4XL.

As big fans of Bombas' socks, we were excited to put the brand's underwear to the test. After giving them a go, we appreciated the brand's thoughtful, comfortable, and durable designs. Plus, knowing of their recycling program and that Bombas will donate a pair to those in need makes this underwear a worthwhile purchase.

This pair of no-show, high-rise panties is crafted from a breathable, quick drying nylon-elastane fabric that our tester found quite comfortable. The thin fabric clings to your curves, so it stays well hidden even under leggings. It comes in three colorways in sizes XS-2X.

Since we love Everlane's clothing and shoes so much, we are happy to report that the brand's intimates are equally impressive. When we took the label's ReNew Underwear — which includes minimalist, seamless styles made from 100% regenerated nylon — for a test run, we found it comfortable and flattering. 

Among the styles that scored high marks with our team is this cheeky, high-rise style, which comes in five shades in sizes XXS-XXL. Executive Editor Sally Kaplan loves the "ultra-lightweight and breathable" fabric. "They don't slip or slide around, which is usually my issue with this kind of silky underwear."

This high-rise style with a full-coverage back stands out for its ability to stay in place no matter your activity. "They stay up and don't roll down," one user wrote of the "soft and comfortable" EBY seamless panties. "The seamless finish is perfection. Love the high rise for added tummy support." They come in seven solid colors and two prints in sizes XS-4X.

Old Navy's underwear section provides high-quality intimates that are easily affordable. This no-show bikini comes in 12 colors and patterns in sizes XS-4X. It's crafted from a seamless nylon-Spandex fabric that sits at your belly button. 

Users love the "great fit" of this pair, with one noting that the undies are "a little on the cheeky side." Another explained: "I've been searching for new underwear now that I'm postpartum, specifically seamless and high waisted to help with covering my belly. I had a c-section so low-rise underwear hurt! These are perfect!"

After working as a Victoria's Secret panty designer for a nearly a decade, Jessica Krupa was disturbed by the chemicals, cheap materials, and synthetic fibers that were applied to women's panties. She teamed up with New York Gynecologist Alyssa Dweck to create Panty Promise, a line of panties that delivers in both style and hygiene. 

This cheeky, high-rise design is made of organic cotton and elastane, with a 100% organic cotton liner. Users report the fabric to be extremely comfortable. The underwear comes in four nude hues, plus black and white, and it's available in sizes XS-4X. 

"My vagina has been so much happier and healthier since wearing these panties," raved one reviewer. "These are definitely the MVPs of my underwear drawer."

Available in a five-pack for under $20, this seamless, high-rise bikini with moderate back coverage comes at an unbeatable price. Users love that the nylon-Spandex fabric "doesn't wedge up" and that the wide waistband offers "slight tummy control." It comes in sizes S-XXL.

If you like your underwear to add a bit of support around your middle, this microfiber high-waisted pair is constructed with a 360° panel around the tummy. Still, they're not constricting like shapewear. "[I] wear a [size] 10/12 and ordered a large," one user reported. "They are snug, not tight and not uncomfortable. I can still [breathe] and sit comfortably. I even wore them to sleep." They come in beige or black in sizes S-XXL.

Harper Wilde's hip-huggers, available in black and two nude shades in sizes XS-4X, wraps itself around your natural curves with an edgeless, silky fabric that's virtually invisible underneath your clothing. The zero-elastic design prevents the underwear from digging into your skin as you wear it. Still, they "don't shift around when I'm wearing them," one satisfied customer reported.

The perfect mid-way option between a thong and a bikini, these cheeky bottoms (on our list of the best cotton underwear for women) offer a seamless look that won't get stuck in body crevices. Aerie offers them in six shades in sizes XXS-XXL.

Many seamless undies are made from nylon for a luxe invisible look, but Hanro proves that you can have that same smoothing effect with a breathable fabric. Made from lustrous cotton, this seamless pair gives a commando look, even under a tight bodycon dress. Amazon users call them "feather light, invisible under clothes, cool, [and] comfortable." They come in six hues, in sizes XS-XL.

In our tests, this pair of Bombas'athletic underwear stood out for it's "silky feel" and "comfortable" low-rise fit, according to Executive Editor of Insider Reviews, Sally Kaplan. The nylon-elastane undies even have a grippy, textured detailing on the inside that's intended to keep the underwear from moving around when wearing under leggings or other activewear. They come in 12 neutral and bright hues in sizes XS-2X.

We asked three testers of different body types to try Negative Underwear's luxury intimates to see how they compared to our favorites among the best underwear for women, and they all fit each wearer well. If you're looking for a bikini silhouette with a bit more coverage and that invisible feel, this low-rise boyshort is an excellent choice. Available in black or tan in sizes XS-XXL, the undies are crafted from a lightweight, barely-there fabric with bonded seams that blends into your skin to hide panty lines.

If you're willing to splurge on a pair of luxurious underwear, Wolford makes our favorite high-end pair of the best cotton underwear. These stretchy cotton briefs — which come in black or rose tan in sizes XS-L — offer full coverage in the back with a low-rise fit in the front with extra stretch around the waistband and leg openings for more flexibility. They'll vanish underneath whichever outfit you choose for the day.

Everlane is among our favorite underwear lines, and the brand's aptly monikered Invisible Bikini is the perfect choice for days when you need to keep panty lines concealed. The recycled nylon-elastane style comes in four hues in sizes XXS-XXL. Users enjoy the breathable fabric and comfy fit, however, they report that the underwear runs a bit small, so you may want to size up.

GAP's no-show bikini scores major points for its super smooth nylon-elastane fabric, seamless and stitchless design that lays flush against the skin, and wallet-friendly price tag at three pairs for $21. Available in 10 subdued colors, the undies (in sizes XXS-XXL) are "truly no-show," one customer wrote, adding: "They work so well under skin-tight dance costumes."

"They not only look good under tight, form-fitting clothing, but also feel really nice on my skin," one user wrote of these cotton-elastane undies by Intimissimi. These seamless stretch panties have scored top marks for both comfort and quality, and come in in 11 bright and neutral colors in sizes S-XL.

MeUndies is among our favorite underwear brands for women thanks to their softer-than-soft materials that are sustainably sourced and breathable. Plus, their designs come in a number of fun colors and designs. For example, this no-show hipster pair comes in seven classic hues (such as black and gray) as well as 23 colorful prints, including a lime green with bicycles and a tie-dye blue. 

Beyond their fun appeal, the undies are impressive for their quick-drying, odor-resisting, super stretchy nylon-elastane fabric (with a cotton gusset), which makes them perfect for wearing under your leggings to a workout class. "When I first got them I was actually nervous about how light they were, thinking they might rip easily or be too delicate, but they hold up well to movement," one customer reported. "They practically feel weightless."

Commando's Butter Bikini is made from a delightfully smooth modal-elastane fabric that feels just like, well — butter. Raw-cut, elastic-free edges on the low-rise, stretchy undies prevent digging, rolling, and bulging. "I barely feel them when I wear them," one user wrote, while another dubbed them the "most comfortable underwear I have ever bought."

Several members of our team have conducted extensive testing on several underwear brands. Each one we've had positive experiences with have proven to be comfortable and fit different bodies. We also suggested pairs made of high quality material that have withstood years in the wash.

For each pair we tried ourselves, we tested to see how invisible they looked by wearing them under thin, light-colored fabrics in direct sunlight. Beyond our own recommendations, we pored over positive reviews to see how customers truly felt about pairs they've tried themselves.
