Frequently Asked Questions

We know, right? It’s partly because of the clever construction, partly because of the first-rate fabric blend, and partly because it supports your body without feeling constricting.

They're both! We’re glad you asked. Think of them as a combination between an old-school slip, a boxer brief and biker shorts: 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.

Perfect

Bought for wearing under skirts, which they're great for, and now I basically live in them as lounge wear. It's true to size, but since I'm XL+ I should've gotten a size up. Still great! Just learn from my mistake ♥️

Great product and fast response when contacted about damage

These fit great, 7" is a great length for under knee length dresses or longer, but may be too long for short dresses. Mine arrived with a small hole in the seam I emailed their info team and got a response 2 hours later, offering the option of a refund or a replacement (I really appreciated the option!) and I went with a replacement because besides the hole it fit well and they even let me change it to a 5" because I wanted it a little shorter. Overall great product and company!

A Summer Essential

These shorts are truly a summer essential. They're lightweight, breathable, and, most importantly, incredibly comfortable. The stretchy fabric moves with you without feeling restrictive, and they stay in place without bunching or rolling down. They're the perfect layer under skirts and dresses, keeping you comfortable and confident all day long.

Extremely comfy!

A blogger I follow recommended these slip shorts and I decided to give them a try- so glad I did! They are very comfortable and best of all, the thighs don’t roll up like some other brands I’ve tried. They wash nicely too (I hung to dry as I do all of my lingerie). Will buy more!
