Why Seamless Underwear Is the Closest Thing to Going Commando

There's something undeniably satisfying about underwear that does its job so well, you barely notice it's there. That's where seamless styles enter the chat—the closest thing to wearing nothing without, well, actually doing it.

Whether it's intimates that disappear under your clothing or a pair of high rise undies that hold it down on your heaviest flow days, seamless underwear is all about blending in while standing up to whatever your day throws at you. There's a time and place for lace, but when it comes to women's seamless underwear, we're leaning into natural fibers, spandex and cotton blends that disappear under our favorite outfits and fit like a second-skin.

From light days to heavy days, from work to workouts, there are seamless underwear styles for every moment. Since our seamless undies are available in just about every size (from XS to XXXXL), the trick is finding the pair that fits your life—and your flow.

Below, we break down five of our favorite undies that prove comfort and functionality can go hand in hand (or hip to hip) for a perfect fit.

The Light Leakproof No-Show Boyshort is the ultimate go-to seamless underwear for days when you want a pair of briefs with a barely-there feel.

Whether you're rushing to the office or lounging at home, its soft, buttery fabric make it feel like it's barely there—until you need it. This is your all-day, move-with-you boyshort that's as versatile as your daily routine.

Say bonjour to the Leakproof UltraThin No-Show French Cut, where timeless style meets serious functionality.

When it comes to seamless panties, there's something about the French Cut that feels a little bit glamorous, even when your day is anything but. Maybe it's the high-cut leg that adds a bit of length, or the way it disappears under your high-waisted jeans like it was meant to be there.
