Read on for the best seamless underwear.
Best Overall: Calvin Klein Invisibles Hipster
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.

"Parade's smoothest fabric ever molds to the shape of your body for a second-skin feel." Not only are they super soft, but they also offer a wide size range. Another plus?

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).

Best Nonslip: EBY Seamless Brief
Various color options

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.

It's simple—and, well, skimpy—design is perfect for those who don’t care for coverage or support but prefer not to go commando. Something to note is that 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.

Hygiene is also a top priority here, with an antimicrobial and sweat-wicking lining to keep you comfy at all times.

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 OEKO-TEX 100 certified, which means it’s been tested for potentially harmful chemicals.

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.

Parade’s Brief Sport+ has all the ingredients needed to make comfortable activewear: sweat-wicking, cooling, edgeless, 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 sesh 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: Blush, Acid, Starry Sky, Magic Berry | Size Range: XS-3X
What to Look for in Seamless Underwear
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, durable enough to wear for years, 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, so understand this as you shop for underwear. If you have sensitive skin, bamboo viscose is hypoallergenic and may be a better choice over spandex. If your priority is product lifespan, modal may just be your best option. Additionally, options with mostly or all nylon tend to be less expensive, since nylon is one of the most cost-effective fabrics.
Not every cut will suit each wearer the same, so it’s important to consider the styles in which you’ll be most comfortable in your prospective outfits. For example, a high-waisted hipster and a boyshort might work equally well as the underpinning for a sheer mini dress, 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 just as 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.
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 form-fitting clothes, like leggings, bodycon dresses, or jeans. They are meant to be stretchy, raw-edged, and are 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’s less stretchy, breathable, water-absorbent, and wrinkle-resistant.
