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.”
Byrdie Researched & Approved
We chose Calvin Klein’s Invisible Hipster as our top pick because they are tried-and-true by the Byrdie team. They’ve garnered thousands of positive reviews on Amazon.

We conducted hours of research on the best seamless underwear, evaluating different styles and brands on their fabric, fit, and size range. After consulting style experts and considering dozens of top-rated seamless underwear, we landed on the following best in show.

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.

Another plus? Parade gives 1 percent of sales to organizations dedicated to social good. Erika Harwood, Byrdie’s Senior Style Editor is a fan. She says, “When in doubt, I always end up reaching for a pair of Parade’s buttery soft undies. They feel like you’re wearing nothing and come in the most vibrant colors.”

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.

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, a 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.
How We Researched
To compile this list, our team of editors and contributors spent hours researching the best products on the market in this category, evaluating their key features—like materials, shade range, or design—in addition to reviews from customers and other trusted sources. We then used this research to assign a star rating from one to five (five being the best; one being the worst) to certain products on the list.
