Visible panty lines aren't as much of a perceived issue as they used to be since the mind-blowing realization that we all wear them — or most of us do, anyway. But if you’re not a fan of panty lines, the best seamless underwear offers the continuous silhouette and imperceptible line you’re going for, even under tight or sheer clothes. This underwear is typically made of a stretchy, lightweight-yet-durable material like nylon, spandex, viscose, or a blend for that smooth line under your clothing. They’re also free of seams (obviously) and tags that can interrupt the silhouette — and they happen to be among the most comfortable underwear you can get your hands (and butt) on.

Seamless underwear is not the sole jurisdiction of G-strings and thongs, contrary to what you may believe. Rather, these invisible undies come in every style imaginable — hipsters, bikinis, shapewear, boyshorts, and all manner of full-coverage underwear included, in addition to comfortable thongs — so the best seamless underwear for you depends on your preferred fit and coverage. That said, every pair of underwear on this list has been approved by editors and savvy shoppers alike for their comfort, breathability, and invisibility even under paper-thin, transparent, skin-tight, or otherwise barely-there articles of clothing.

With all that in mind, scroll on to shop the best seamless underwear that will keep you panty line-free, no matter what you're wearing.


This Multipack Of Seamless Thongs With Over 43,000 5-Star Ratings

— Also available on Walmart, $24

This five-pack of seamless thongs are an undeniable favorite on Amazon, where reviewers praise their buttery-soft fabric and barely-there feel. Despite the low price tag, customers confirm that the quality rivals more expensive brands. These are made of nylon and elastic mesh for a silky, lightweight feel, but the gusset is lined in cotton to keep them breathable. Choose from several color combinations, including neutrals, brights, and playful patterns.

What reviewers say: “These are *actually* seamless and very comfortable. I trust these thongs.”

  • Available sizes: XX-Small — XX-Large


These Ribbed Hipster Panties That Are So Comfortable

These ribbed hipsters from Bombas will likely become your favorite everyday underwear. Made from nylon, modal (a soft cotton-like fiber), and a bit of spandex, these seamless panties provide coverage and comfort. Without any tags or seams, they won’t dig into your skin or show through your clothes either. Reviewers note they hold up great over time so you’ll definitely be getting your money’s worth. Choose from a range of colors and sizes.

What reviewers say: “I was pulling my hair out 2 years ago trying to find plus-size underwear that fit and was comfortable. Nothing I found seemed to work. They were too big, too small, or had tortuously uncomfortable seams that cut into my hips. I felt doomed. Then I found Bombas! They're absolutely perfect! They fit well, are extremely comfortable, and last for years.”

  • Available sizes: X-Small — 2X


These Sweat-Wicking Hipster Briefs That Keep You Dry During Workouts

— Also available on Sam’s Club, $14

Whether you’re looking for a pair of full-coverage undies to wear during a workout, or you live in a hot climate, these Reebok hipster briefs literally have you covered. The material (a blend of nylon and spandex) is silky yet strong — similar to yoga pants, according to one customer — and they’re wildly comfortable. No bunching or rolling, even under tighter bottoms. They won’t totally disappear under leggings (only a thong will do that), but they’re much less visible than typical hipsters.

What reviewers say: “These briefs are so comfortable--no slipping or sliding. Don't show under leggings. Wash and dry on low and come out like new. I threw all my old ones away and replaced with these.”

  • Available sizes: Small — X-Large


These Soft & Stretchy High-Waisted Hipsters

There’s no need to settle for underwear that pokes, constricts, or squeezes. Instead, these high-rise ribbed hipsters from Bombas comfortably wrap around your hips and lower tummy to provide full coverage where you need and want it. Fans especially love these panties for their support, stretch, and fit with one reviewer describing them as “not too tight or too loose.”

What reviewers say: “I've been looking for new underwear, and I love these. Comfortable, breathable, and with enough fabric that I feel covered. Will definitely buy more, and recommend to everyone.”

  • Available sizes: X-Small — 2X


A Set Of Full-Coverage Bikini Panties In A Fun Leopard Print

If you adhere to the “all-black everything, except for your underwear” mindset (same), add these adorable leopard-print bikinis to your cart. Their nylon-and-spandex material and laser-cut construction keeps them comfy, stretchy, and totally seamless, even under leggings; but the gusset is lined in cotton, so you can wear these comfortably while you sweat. These also come in assortments of neutrals and solid colors, if you prefer more subdued underthings.

What reviewers say: “[...] These are truly seamless and sooo comfortable!! They fit just right. The colors are good-variety also. Happy with this purchase so far.”

  • Available sizes: Small — Large


These Comfy High-Cut Briefs At A Great Price

— Also available on Walmart, $17

Just $17 gets you six pairs of Fruit of the Loom undies in a classic brief cut (i.e., full-coverage over the butt and cut high on the waist). These 100% nylon panties are completely smooth and free of tags, which are both annoying and interfere with that seamless look. If you prefer a different cut, you can also get a 6-pack of hipsters, bikinis, or low-rise briefs on the same page, all featuring the same smooth material and seamless construction.

What reviewers say: “These are the most comfortable underwear ever. Extremely lightweight, and best of all no tags or stiff and obtrusive seams that irritate the skin. Very stretchy as well.”

  • Available sizes: 5 — 13 Plus


These Featherweight Thongs That Are Comparable To SKIMS

If you love the look and feel that SKIMS offers, you’ll also love these seamless thongs from Amazon Essentials. The reviews section is rife with customers comparing them to SKIMS and LuluLemon for their stretch, quality, and comfort. The material is a blend of nylon and spandex for a barely-there feel but has a sturdy stretch that makes you feel secure. Each four-pack comes in a range of colors — from cool pastels to warm neutrals — wide enough to satisfy every aesthetic.

What reviewers say: “Yea I said that. These are way more comfortable, durable, and thicker than SKIMS. Not to mention the price point. These go good with workouts, runs, smooth lines jeans, just about anything. I work in a bar so they didn’t ride up and stayed where they should.”

  • Available sizes: X-Small — XX-Large


These Seamless Boyshorts From A Classic Underwear Brand

— Also available on Walmart, $17

Hanes underwear has been a longtime go-to for comfortable, great-quality underwear at a surprisingly affordable price. Case in point: These seamless boyshorts that cost a little over $2 a pair, but will last you for years. Hailing from the brand’s ComfortFlex Fit line, these boyshorts feature a stretchy-yet-durable fabric that naturally hugs and defines your curves, and their seamless waistband and leg openings defy rolling or bunching. These are even forgiving enough to accommodate growing pregnant bellies, according to customer reviews (but plenty of customers who aren’t pregnant are obsessed with them, too!). The smooth shorts are a great solution for thigh chafing, too.

What reviewers say: “These boy shorts are very comfortable and do not ride up at the leg like I thought they would. Waist band is perfect. Plus there are no seams!!!”

  • Available sizes: Small — XX-Large


These Hipster Panties That Show Some Cheek

— Also available on Calvin Klein, $23 (3-Pack)

These panties from Calvin Klein offer a good amount of coverage over your butt, but they’re cut a touch higher than you may expect to reveal a bit of cheek, and they sit a little higher on your waist than other hipsters — all told, a great balance between comfort and sexiness. A name brand at the hip is a subtler touch on Calvin Klein’s signature branding, as well. And with a seamless waistband and nylon-elastane material, these are divinely lightweight and virtually invisible. These fit fairly snug, so some reviewers recommend sizing up.

What reviewers say: “I only wear Calvin Klein undies because they fit so well, and these are exceptionally comfortable. They're seamless so it's my go-to thong alternative. Comfortable and fits like a second skin.”

  • Available sizes: X-Small — X-Large Plus


This Colorful Set Of Six Seamless Boxer Briefs

— Also available on Walmart, $31

If you want to stock up on several seamless options, snag this set of six boy briefs. Made from spandex and nylon, and free of itchy tags and side seams, these undies are super soft and stretchy for all-day comfort. Plus, they maintain their shape and fit even after several washes, according to Amazon reviewers.

What reviewers say: “These are my new favorite underwear! Taking them out of the package I was worried because they look really small but they have amazing stretch to them! My butt is huge and boy shorts usually leave my cheeks hanging out but with these I have full coverage! The waistband never rolls down and they are so breathable!”

  • Available sizes: 1X — 4X


This Underwear That One Reviewer Calls “The Best Pair Of Underwear I’ve Ever Worn”

— Also available on Sam’s Club, $15

These full-coverage briefs from Ellen Tracy are smooth and seamless-cut, so you can rest assured they won’t peek through any body-conscious outfits. The panties rise to just below the belly button and they’re stretchy and non-binding — i.e., comfortable enough to wear all day, every day. Choose from fun colors like calypso pink, or opt for neutrals like black, white, and beige.

What reviewers say: “I have tried several different brands of underwear including Victoria’s Secret, Hanes, Adoreme, and Tommy Johns. These are BY FAR THE BEST and most comfortable I have every had. They wash up great! I will not own anything but Ellen Tracy.”

  • Available sizes: Small — 3X


Editor’s Pick: These Calvin Klein Thongs That Feel Totally Weightless

— Also available on Calvin Klein, $25

Associate Commerce Editor Caroline Goldstein says: “After many, many years of wearing thongs, I can confidently say that these from Calvin Klein are my favorite. They’re made of a super-smooth, flexible material that’s truly invisible under tight clothing, but a cotton gusset keeps them breathable (they’re my go-to for wearing under leggings during workouts). The gusset, waistband, and back are wide enough to feel comfortable and secure — nothing at all like the dental floss G-strings I’ve also experimented with (which serve their own purpose, to be sure, but which I don’t really want to wear every day). They hold up beautifully in the washer and the dryer, as well. I stock up on these in packs of three, and by now, I have them in pretty much every shade there is, though the white and neutral shades are especially useful for light-colored or sheer clothing.”

What reviewers say: “These are super soft and comfortable. Feels like I’m not wearing anything. Actually seamless, good basics color variety. Why did it take me 30 years to buy my first Calvin Klein undies, I’ll never stray from this brand now. Worth the price! True to size.”

  • Available sizes: X-Small — X-Large


A Set Of Stretchy Briefs Made Of Ultra-Breathable Bamboo

Although cotton (or a cotton-lined gusset) is the classic choice when you’re shopping for breathable underwear, bamboo is just as soft and breathable, and it has four times the moisture-wicking effects as cotton does. It happens to be a sustainable fabric, too. Which all makes these Warm Sun panties ideal for those seeking a full-coverage option to wear during a workout, in hot or humid weather, or those who simply tend to sweat. This pair is blended with 5% viscose for stretch and a seamless fit.

What reviewers say: “These are amazingly comfortable! I want more. The beige is great for under white clothing, and no panty lines.”

  • Available sizes: 4 — 10


A 6-Pack Of Seamless Thongs With Pretty Lace Detailing

Granted, the lace detailing on these no-show thongs might show a tiny bit if you’re wearing very tight and/or sheer clothing, but their polyamide and spandex construction makes them much more seamless than your typical lace thong. Several Amazon shoppers say these thongs also offer good coverage in the front, so they’re incredibly comfortable and don’t ride up. And with colors and prints like coral, magenta, and all manner of florals, they’re just too pretty to pass up.

What reviewers say: “Seamless panties are the only way to go, but I love that these are cuter then the previous ones I have purchased. Have owned for a couple months and they have been holding up great in the wash with no issues!”

  • Available sizes: Small — 5X Large Plus


These Full-Coverage Briefs That Feel A Little Luxurious

— Also available on Bare Necessities, $20

Slipping on a pair of French underwear will always feel luxurious, even if that underwear is unapologetically practical, like these full briefs from Chantelle. Made from luxe stretch microfiber, they won’t slide, roll, or creep up, so you don’t have to worry about wanting to adjust when you’re in public. The laser-cut edges make these panties virtually invisible under clothes. This plus-size pair comes in one size only, though most reviewers report that they truly fit a range of sizes. Pick them up in seven elegant shades, like powder blue, stone, or the classic black featured here.

What reviewers say: “What I love about this product is how it gives the perfect fit for a one size fits all product. It is extremely stretchy so it doesn't dig but stays close to the body. I also love how they don't slip down at all and feel like I am wearing nothing! So soft and so comfortable.”

  • Available sizes: One Size


A 12-Pack Of Laser-Cut Panties In Assorted Colors

If you’re looking for an unbeatable deal, pick up this 12-pack of seamless bikinis that costs just $25 — and with over 6,600 perfect ratings on Amazon, shoppers confirm that these don’t skimp on quality. They’re silky-soft, “fit like a glove,” have amazing stretch, and their laser-cut construction keeps them virtually invisible, even under leggings. Get them in an assortment of solids, prints, or all black, or in a style that features sweet ribbed detailing and a scalloped hem.

What reviewers say: “Really truly seamless! No seam even at the gusset. I wear these under yoga pants and they really can't be seen. I also like the reinforced waist band; it doesn't roll down the way many other laser cut ones do.”

  • Available sizes: Small — X-Large
