Frequently Asked Questions

Well, to start, they’re silky smooth under any outfit. But more importantly, if you run hot—and are one of those people who’s constantly setting the thermostat to “meat locker” temperature—these are going to be a revelation.

Our slip shorts are made of hi-tech fabric that lowers the body temperature. (If you want to get geeky about it, the flat cross-section of the yarn offers a wide surface area that quickly releases body heat from your skin.) The yarn texturizing process gives the shorts incredible breathability; the finished ultra-thin fabric is a breeze to wear, literally.

They're both! We’re glad you asked. Think of them as a combination between an old-school slip, a boxer brief and a bike short: They give you coverage under short or too-sheer outfits, stop your inner thighs from trying to start a forest fire, and light smoothing with no VPL (the word “panties” weirds us out, too). Plus, the knit-in cotton-rich crotch means you can wear them without underwear if you want, eliminating the need for an extra layer.

Thigh Society shorts don’t compress you or suck you in like shapewear. Instead, they’re a lightweight, breathable, sweat-wicking essential you’ll reach for again and again.

Flexible and stretchy, our waistband is made from the same fabric as the shorts, just double-folded and sewn-in. It stretches to your curves, never cuts into them. The waistband is like the Loch Ness Monster: you’ll doubt it really exists.

Our sheer leggings offer the moisture-wicking and cooling experience of our shorts with more leg coverage.

Just as advertised!

So great to wear under dresses and skirts! Does not rise and can't even feel they're there. Will definitely need another pair before next summer.

Field Researcher Wants MORE

I conduct anthropological field research in some of the most remote areas of the world. Most of them are hot. I mean, really hot. I was gifted a pair and immediately bought two more. They are EXCELLENT at protecting from chafing and wetness. They cool and help prevent odor. We're literally sometimes in the hottest of jungles and these shorts improve the experience. Thank you!
