When you find the perfect pair of seamless underwear, it’s like finding a new and true friend. It allows you to feel comfortable and confident in the way you look and move, and you can trust that when it makes a promise (e.g., to keep you line-free in every outfit), it’ll pull through every time.

Tamara Conlin, vice president of Product Operations & Strategy at Parade, offers some guidance if you're in the market for this aforementioned pal. "True seamless underwear has an edgeless design—no lines under clothes, even leggings," she says. "When shopping for seamless underwear, it's best to look out for these second-skin materials and fabrics, and to find a pair that shows no lines at all."

That said, it’s also important to remember that the underwear won’t all feel the same; how much comfort they offer will vary from product to product. Keep your preferences and needs in mind when shopping around, and to help guide you further, we have scoured the internet and tried several pairs to find la crème de la crème.

Read on for the best seamless underwear.

Calvin Klein’s “invisible” underwear is everything we could want in a pair of seamless underwear. They’re comfortable enough to wear all day and night; they’re lightweight for a barely-there feel while still being resilient enough to last for years; and most importantly, they’re truly seamless—complete with clean edges—so they don’t show under clothes. Let’s not graze over the fact that they come in a plethora of colors and prints, so you’re sure to find the right pair for any mood.

  • Good stretch

  • Very lightweight

  • Adapts to body shape

What We Don't Like
  • Faintly detectable panty line

For those who gravitate towards a fuller-coverage hipster style, this is Byrdie’s best recommendation. According to the brand, these are the world's first carbon-neutral edgeless underwear. "Universal is made with OEKO-TEX-certified recycled fabrics and utilizes a 100 percent organic cotton gusset," explains Conlin. "Parade's smoothest fabric ever molds to the shape of your body for a second-skin feel." Not only are these underwear super soft, but they also offer a wide size range. Another plus? Parade gives 1 percent of sales to organizations dedicated to social good.

What We Like
  • True to size

  • Smooth waistband

  • Breathable

What We Don't Like
  • Doesn't hold up after some washes

This pack of seamless underwear by Fruit of the Loom is a budget score given the price for a pack of six and is beloved by reviewers. The brand boasts a stretchy fabric and tag-free construction for all four styles—bikini, high-cut, hipster, and low-rise brief—in its seamless line. We also appreciate the cheery pink and purple colorways, which are great if you’re bored of the typical nude and black variety packs. For an everyday no-show panty with little effect on your shopping budget, these tick off every box.

Material: 100% nylon | Colors: Assorted pinks and purples, Black | Size Range: 5-9

What We Like
  • High recovery

  • Elastic-free construction

  • Piling resistant

What We Don't Like
  • Has to be washed cold

Per the name, these panties by Commando are buttery soft with an elastic-free construction for a very breathable feel. Produced from luxury Austrian modal, they feature four-way stretch with a high recovery capability, meaning they snap back after all-day wear. They’re a great value not only because of their construction and comfort but for their longevity (they’re pilling resistant) and sustainability (they're made from renewable beech trees). 

Material: 79% modal, 21% elastane | Colors: Black, Beige | Size Range: XS-XL

Best Nonslip: EBY Seamless Brief

eby-seamless-brief

EBY

What We Like
  • No-slip grip

  • Buttery soft

  • Various patterns and prints

What We Don't Like
  • Not many super petite sizes

EBY is fairly new to the underwear scene, but it's making its mark on the industry. Co-founded by Sofía Vergara, the brand's seamless brief is a solid go-to thanks to the nylon no-slip grip (so there's no silicone chafing), buttery soft material, and comfortable fit. If you need your undies to stay in place, whether you're headed to yoga or the office, these won't let you down. Plus, EBY funds microloans for women to start their own businesses as a way to get out of poverty, so you know your purchase is contributing to a good cause.

What We Like
  • Gently hugs curves

  • Cooling

  • Sporty mesh patter

What We Don't Like
  • Runs a bit big

For a luxury brief, look to Wacoal. In addition to light shaping, this particular pair of briefs apparently offers a cooling feature in high temperatures. It’s the ultimate pick to support an outfit for an all-day event where you’ll need to be cool and comfortable for hours on end. It’s worth noting that the brand recommends hand-washing and line drying these briefs.

It’s available in four neutral colors to match every outfit’s necessity, but it also comes in Sea Salt and snake print for a dash of personality.

Intimissimi Brazilian Panties in Seamless Ultra Light Microfiber
What We Like
  • Ultralight

  • Breathable

  • Soft pastel shades

What We Don't Like
  • Tends to ride up a lot

Intimissimi's simple—and, well, skimpy—design is perfect for those who don’t care for coverage or support but prefer not to go commando. This particular style has a limited size range, so if you’re on either end of the spectrum or in between sizes, it may not be the perfect fit for you. A benefit of Intimissimi? Traceability. According to the brand, they produce 94 percent of goods in their factories with complete control of the supply chain. 

Material: Microfiber | Colors: White, Black, Soft Beige, Silk Pink (off-white), Medium Beige, Candy Pink +more | Size Range: S-L

What We Like
  • Flattering back V-shape

  • Sweat-wicking

  • Maximum wearability

What We Don't Like
  • Not as many petite sizes

These bikini briefs in modal are easy to wear every single day due to their comfort and versatility. While not technically seamless, the style’s back "V" shape makes it perfect for those looking for minimal coverage of the derriere. Plus, CUUP assures prospective wearers that it lies flat both high on the waist and low on the hips for maximum wearability. Hygiene is also a top priority here, with an antimicrobial and sweat-wicking lining to keep you comfy at all times.

Material: 88% modal, 12% elastane | Colors: Black, Salt, Espresso, Blush, Taupe, Clay, Marigold, +more | Prints: Leopard | Size Range: XS-XXXL

Best Compression: SKIMS Sculpting High Waist Brief

Skims Sculpting High Waist Brief
What We Like
  • Prevents rolling

  • Effectively shapes and lifts

  • Very comfortable

What We Don't Like
  • Pricey for just one garment

  • May show under clothes

SKIMS seeks to enhance your body’s natural shape with its Sculpting High Waist Brief in a seamless construction. The brand claims invisibility under every garment and plenty of support around the core and butt. And since this style runs up to the bustline, it also features a silicone grip along the waistband to prevent rolling. Like virtually all of SKIMS's offerings, this brief comes in nearly a dozen skin tone colors.

Material: 78% nylon, 22% spandex | Colors: Sand, Mica, Clay, Ochre, Sienna, Umber, Oxide, Cocoa, Onyx | Size Range: XXS-5X

Best High-Waisted: CUUP The Tap

Cuup The Tap
What We Like
  • Quality feel

  • Just the right amount of coverage

  • Bold and bright colors

What We Don't Like
  • Tend to stretch out quickly

For full coverage and a flawless fit, look to CUUP’s high-waisted, low-hip style. Its mesh material is designed to be breathable, and its ultrasonic line bonding technology allows for its sew-free finish. The brand promises that wearers won’t experience digging in this style—or any other style, for that matter. And for those interested in a more traditional seamless-like material option, this style is also offered in modal. Either way, they’re perfect for layering under thin or sheer dresses and skirts or simply lounging at home with the most comfort.

Material: 79% polyamide, 21% spandex | Colors: Espresso, Salt, Taupe, Clay, Black +more | Size Range: XS-XXL

Intimissimi Invisible Touch Hipster
What We Like
  • Seamless edging

  • "Barely there" feel

  • Beautiful pastel and nude shades

What We Don't Like
  • Limited size range

Intimissimi’s Invisible Touch Hipster takes a unique approach to barely-there underwear. Its tulle-like fabric makes it soft and comfortable for wearers, and the seamless edges create a no-show effect. These would particularly be a comfortable pairing with slim-fitting high-waist trousers or skirts; however, be conscious of the brand’s more limited size range.

Material: Front: 57% polyamide, 43% elastane; Back: 70% polyamide, 30% elastane; 100% inner cotton gusset | Colors: Black | Size Range: S-L

  • Smaller size range

  • Has to be washed delicately

This Italian-made free-cut thong is both comfortable and versatile enough to be worn daily. The style is designed to sit above the hip bones to complement your natural curves without any visible panty lines. Fun fact: The brand claims to have coined the term “No More VPL” back in the mid-1980s, so you could say they have experience in perfecting it.

Material: Body: 80% polyamide, 20% elastane; Inner gusset: 93% cotton, 7% elastane | Colors: Black, Cinque, Due, Sette, Tre, Uno, Quattro (skin tones) +more | Size Range: S-XL

Commando Classic Control Thong
What We Like
  • Fast drying

  • Piling resistant

  • Machine washable

What We Don't Like
  • Fits uncomfortably to some

A supportive thong, like Commando’s Classic Control Thong, can be a game-changer. It offers a light to moderate amount of compression so that you may feel supported but not “stuffed.” The raw-cut edges help the nylon-and-spandex garment sit flat and minimize digging. Another plus? It’s crafted from sustainably made fabric, which is PEF-, REACH-, ISO 14001- and Standard 100 by OEKO-TEX certified.

Material: 68% nylon, 32% spandex | Colors: Black, Beige, Caramel, Mocha | Size Range: XS-XL

Best Colors: SKIMS Fits Everybody Thong

Skims Fits Everybody Thong
What We Like
  • Various colors

  • Very wide range of sizes

  • Doesn't dig into skin

  • Doesn't lose color or quality after washes

What We Don't Like
  • Waistband stitching is slightly visible under clothing

SKIMS prides itself on offering an inclusive color selection (as well as size range) for its products, be they an itty-bitty thong or a high-waisted brief. Most undergarments come in eight to nine skin tone colors, plus a handful of seasonal colors. Pro tip: SKIMS products are famous (or rather infamous) for selling out quickly and often, so sign up for waitlist emails to ensure you can grab your size as soon as it’s available.

Material: 79% nylon, 21% spandex | Colors: Nectarine, Sand, Mica, Clay, Ochre, Sienna, Umber, Oxide, Cocoa, Onyx +more | Size Range: XXS-4X

Best Cheeky: Aerie No Show Cheeky Underwear

Aerie No Show Cheeky Underwear
What We Like
  • Fun prints

  • Moisture-wicking properties

  • Affordable

What We Don't Like
  • Shift a bit while wearing them

For Aerie, “no show” means no visible panty lines, period. With its No Show Cheeky style, it promises no lines anywhere, even if you’re in leggings. In terms of material, the combination of nylon and elastane makes this underwear stretchy and lightweight. In fact, it’s the brand’s most lightweight fabric. It also contains wicking properties to keep you dry when you sweat; in other words, these are fitness class-friendly. 

Material: 87% nylon, 13% spandex | Colors: Midnight Sky, Dawn, Deep Plum, True Black +more | Prints: Fire, Green Mission | Size Range: XXS-XXL

What We Like
  • All-day support

  • Light sculpting compression

  • Function, feel-good details

What We Don't Like
  • Only comes in one color

If you just baked a bun and you’re looking for something seamless to smooth things out, check out HATCH's Seamless Belly Brief. It offers full coverage and support with light sculpting compression but doesn’t look like a “granny [panty],” according to one reviewer. When figuring out your size, the brand recommends measuring the fullest part of your hips for the most comfortable fit. 

Material: 84% modal, 13% nylon, 3% elastane | Colors: Sand, Black | Size Range: S-XL

Whether you’re seeking the perfect pair of shorts for sleeping or an undergarment that will give some extra coverage under a minidress or skirt, this seamless modal pair by Lunya is here for you. Composed of Lenzing modal, nylon, and elastane, it’s designed to hug the body and maintain a supportive fit. It lacks side seams, which reduces the possibility of chafing.

Material: 70% modal, 23% nylon, 7% elastane | Colors: Immersed Black/Otium Tan, Deep Blue/Otium Tan, Meditative Grey/Otium Tan, Sincere White/Otium Tan | Size Range: XS-XL

Along with sweat-wicking and quick-drying properties, they also provide full derriere coverage, making them a great option for workouts or the summer season.

What We Like
  • Streamlined, stretchy silhouette

  • Extra coverage

  • Sustainable construction

What We Don't Like
  • Tends to roll down the stomach

For those whose skin doesn’t fare well with typical clothing fabrics, Boody might be a more comfortable option. The Aussie-born brand is known for its use of bamboo viscose, a material that has a host of advantages and is wildly different from cotton. Silky to the touch, this fabric is said to get softer with every wash while still maintaining its shape. The bamboo fibers made in Boody’s bras and underwear are certified Standard 100 by OEKO-TEX, which means they've been tested for potentially harmful chemicals.

Material: 80% bamboo viscose, 13% nylon, 7% spandex | Colors: White, Black, Light Grey Marl, Nude 0, Nude 2, Nude 4, Nude 6 | Size Range: S-XL

  • Very soft, recycled material

What We Don't Like
  • Has glued seams

A great everyday underwear, Everlane’s Invisible High-Rise Hipster is soft and smoothing, perfect for anything from high-waisted jeans to silky dresses. Bonded to lie flat against your skin, they are designed to move with you while preventing annoying (and uncomfortable) bunches that we do not have time for! In addition to being made from recycled nylon, one reviewer was appreciative of its eco-friendly packaging: it arrived in a simple cardboard packet and post-consumer plastic pouch.

Material: 87% recycled nylon, 13% elastane | Colors: Dark Tan, Light Tan, Black, Plum Grey, Pewter Green | Size Range: XXS-XXL

What We Like
  • Non-piling

  • Delivers extra freshness

  • Made from quality material

What We Don't Like
  • Construction produces an odd fit

If you’re one of the few people excited about low-rise jeans coming back in style, this is may just be your new go-to. Tommy John’s Second Skin Boyshort is meant to feel just like that: a second skin. The nonpilling, super soft modal fabric makes it suitable for everyday wear. You can expect comfort despite the hip-hugging rise, too, thanks to a waistband that “won’t roll, bunch, or pinch,” according to the brand. 

Material: 90% modal, 10% spandex | Colors: Peachskin, Maple Sugar, Winetasting, Dress Blues, Black, Cool Grey Heather, Soft Pink +more | Size Range: XS-XXL

Glacé G-String

Negative Underwear

What We Like
  • Silky soft Belgian stretch nylon

  • Non-piling

  • Anti-dig waistband

What We Don't Like
  • Expensive

For those who feel that less is more, the Glacé G-String is worth a try. It's Negative Underwear's most minimal cut and offers an assurance of seamlessness under anything. Silky soft and super stretchy, it's also as comfortable as it gets, according to reviewers. Wear it around the hips or pulled high to the natural waistline.

Material: 23% lycra and 77% nylon | Colors: Black, Buff, Coral, Moon, Peach | Size Range: XS-XXL

Best Active: Parade Thong Sport+

What We Like
  • Durable interlock seams

  • Sweat-tested by real athletes

  • Quick drying

What We Don't Like
  • Middle seam could be better constructed

Parade’s Brief Sport+ has all the ingredients needed to make comfortable activewear: sweat-wicking, cooling, edgeless, and quick-drying. According to Conlin, "Breathability and comfort are of ultimate importance when choosing seamless underwear," which is especially true if you plan on having a sweat session in them. Not only does it both feel and look invisible under leggings and bike shorts, but it’s also been said that they stay put quite well. This all sounds like a recipe for a successful workout class, if you ask us.

Material: Body: 80% recycled nylon, 20% elastane; Lining: 100% cotton | Colors: Zest (yellow), Lime Fizz, Hibiscus, Eightball (black), Amethyst, Deep Sea | Size Range: XS-3XL

What to Look for in Seamless Underwear

Material

Shapewear is generally made from nylon and spandex, though some brands are making the most of modal. The latter has many benefits: It's approximately 50 percent more absorbent than cotton and durable enough to wear for years. Modal also doesn’t pill or shrink in the wash and is eco-friendly because it’s biodegradable and made from plants. Another material featured in this roundup that’s worth mentioning is bamboo viscose. According to undergarment brand Boody, it’s a super soft fabric that feels light and gentle on your skin while also being breathable and moisture-wicking.

That being said, different materials may cater to different needs. Bamboo viscose is hypoallergenic and may be a better choice for you over spandex if you have sensitive skin. If your priority is product lifespan, modal may just be your best option. Mostly nylon and all-nylon options tend to be less expensive since nylon is one of the most cost-effective fabrics.

Cut

Cuts will suit different people differently, so it’s important to consider the styles in which you’ll be most comfortable in your prospective outfits. A high-waisted hipster and a boyshort might work equally well as the underpinning for a sheer minidress, in which case it would come down to whether you feel more comfortable with more material around your core or your butt. By the same token, a seamless thong and a pair of seamless cheeky underwear may not work equally well under a bodycon dress. If you don’t want lines but still need some structure, go for compression or, at the very least, a high-waisted option.

FAQ
  • What is seamless underwear?

    Seamless underwear is designed to hide panty lines, and it can sometimes offer smoothing and compression benefits. A pair of seamless underwear is ideal for when you’re wearing formfitting clothes like leggings, bodycon dresses, or jeans. They are meant to be stretchy and raw-edged, and they're typically made from a mix of cotton, spandex, modal, nylon, or elastane. "Flexible fabrications such as nylon and elastane—both of which Parade uses for its Universal styles, invisible waistbands, and of course, showing no lines when worn underneath tight pants—are important qualities to make a pair of underwear truly seamless," explains Conlin.

  • What’s the difference between cotton and modal?

    Though both are plant-based textiles, cotton and modal have some distinct differences to understand. Modal is a knit-like fabric that’s often used for luxury goods. It’s stretchy, soft, breathable, water-absorbent, durable, and resistant to wrinkles. While cotton is soft, it offers less stretch, breathability, water-absorbency, and wrinkle-resistance.
