Real Simple / Reese Herrington
Nothing messes up a good outfit quite like visible panty lines—but luckily, this problem can be easily solved by wearing seamless underwear. The best pairs of seamless underwear have edge-free designs that are practically invisible underneath your clothes.
“Seamless underwear can be worn under just about anything,” says Kimmay Caldwell, undergarment educator at Hurray Kimmay. “A clean and seamless look helps showcase the lines of the garment instead of the undergarment.” That’s why Caldwell says seamless underwear is “especially great for clingy, thin, tight, or snug clothing—basically any clothing that is prone to show visible panty lines.”
To come up with these recommendations, we thoroughly researched the market and rounded up our favorite pairs of seamless underwear. We considered factors like material, cut (such as thong, bikini, and hipster), and size range, and we also received expert tips from Caldwell on how to choose the best seamless underwear for your needs.
Our top pick is the Skims Soft Smoothing Brief. These panties are sleek, soft, and comfortable, and we appreciate that they’re size- and color-inclusive.
Skims Soft Smoothing Brief
Best Overall Seamless Underwear
Who it's for: People who want a super soft, practically invisible pair of everyday underwear.
Who it isn't for: People who don’t want to hand wash their underwear.
The Skims Soft Smoothing Brief is stylish, reliable, and great for all different body types, which is why it’s our best overall pair of seamless underwear. Available in eight colors (ranging from army green to cocoa, with plenty of skin-toned hues) and a wide size range (XXS to 4X), these simple briefs will quickly become your go-to underwear for everyday use.
The seamless underwear is made from a super soft and buttery blend of nylon and spandex, with a cotton gusset lining that will feel smooth and invisible on your body—no pesky panty lines here. The back has medium coverage, and the brief design works well under all kinds of outfits and materials. Just keep in mind that Skims recommends hand washing this underwear with cold water and line drying to keep it looking new.

It’s made from a combination of lightweight nylon and elastane that’s moisture-wicking and ultra-comfortable. It has a smooth and stretchy feel, with raw-cut edges that won’t show up under any type of bottom (yes, even leggings).

The seamless panties have raw-cut edges and no uncomfortable elastic, so they won’t dig into your skin. You can pick from five neutral colors, though there aren’t any fun colors or patterns.

The nylon material is breathable and quick to dry, and the brief’s cotton gusset is quite comfortable. Though the underwear is machine-washable, the brand suggests laying them flat to dry to avoid shrinkage or damage.

The waist has raw-cut edges and the legs have wide openings to help prevent any panty lines, and the gusset helpfully has a moisture-wicking liner.

Intimissimi Seamless Supima Cotton Panties
Best Cotton Seamless Underwear
Who it's for: People who want seamless underwear made of primarily cotton.
Who it isn't for: People who want underwear that comes in a wide range of sizes.

The seamless low-rise panties will feel soft and smooth on your body throughout the entire day, and you won’t have to fret over panty lines. The only negative is that the size range is unfortunately fairly limited, with just small, medium, and large options.

Boody Classic Bikini
Best Bamboo Seamless Underwear
Who it's for: People who want a silky-smooth pair of underwear made from bamboo.

Due to its natural silkiness, bamboo is another excellent material for seamless underwear. This popular pair from Boody is made from organic bamboo viscose, with a bit of nylon and spandex for stretch and durability. This combination makes for a breathable, odor-resistant, and moisture-wicking pair of underwear.
This pair has a classic bikini design with a flat-ribbed waistband and a mid-rise fit that provides a fair amount of coverage. When you shop on Boody’s site, you can purchase this underwear in sizes ranging from XS to 4XL. Just take note that the material can be a magnet for hair and lint, so you may want to wash them separately from your other items.

The sleek bikini-style underwear has a breathable cotton gusset and silicone at the leg openings so that it stays in place. It also boasts a low-rise fit and a moderate level of back coverage. There are 25 different colors to choose from, so the options are practically endless.

How to Shop for Seamless Underwear
Material
Many pairs of seamless underwear are made from nylon, which is a soft, stretchy, and typically thin material. Other common materials for seamless underwear include cotton, lace, and bamboo—the latter of which is ideal for sensitive skin. These types of underwear are often made with fabric blends, meaning they may also contain spandex or elastane for added stretchiness.
Cut
Seamless underwear is available in various cuts, ranging from thongs to bikinis to briefs. Each style provides a different amount of coverage and feels different on your body, so think about how much skin you want to show and how supportive you want your underwear to be when considering the cut of your seamless underwear.
Colors
Like all underwear, seamless pairs come in tons of colors—and whichever options you choose depends on your personal taste and needs. Neutrals and nudes can be great for clothing that’s less opaque than others. (When wearing white pants, you should wear underwear in a color that matches your skin tone.) On the other hand, bright colors and bold patterns can simply feel more fun.
Questions You Might Ask
What’s the difference between seamless and no-show underwear?
“All seamless underwear is meant to be no-show, but not all no-show underwear [is] seamless,” says Caldwell. Some no-show underwear, for instance, have seams at the hip or top to ensure a tight fit, while others may have seams underneath despite a smooth, lineless look on the outside. “True seamless underwear has no seams whatsoever,” Caldwell explains, who adds that they are made from “one piece of material with no cuts or seams.”
What’s the best type of seamless underwear to wear under leggings?
“Thongs work great for this,” says Caldwell. The smaller amount of material means there’s less of a chance that you’ll get panty lines or have any part of the underwear showing through. But if thongs aren’t your preferred style, all high-quality seamless underwear should work well under leggings and not cause panty lines.

How do you keep seamless underwear from rolling and riding up?
“First, make sure you're wearing the right size!” says Caldwell. “Too many folks buy a size too big to try to avoid digging in, but then the fabric just roams around. Or they'll buy a size too small and it just digs in or doesn't cover the bum adequately so it rides up or rolls down at the waistband.” After that, make sure the underwear is “the right cut for your body,” she adds, which might mean experimenting with some different coverage styles.
