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.

Original 7inch

I am super happy with these! I already have 2 pairs in black that I wear as pajama shorts, so I knew I would like them. The black ones I have are 9inch and have the cargo pockets. I love the beige pair for under dresses in the summer. I like that the 7inch is a bit shorter, so it is less likely to be visible. They are super comfortable and modest. I won’t wear a dress without my Thigh Society shorts!

Perfect for hot summer weddings

These arrived right in time for an outdoor wedding and I’m so glad I took the plunge and invested in these. They are opaque but perfectly lightweight and didn’t bunch or roll at all. I was so comfortable in these and am so glad I wore these instead of restricting shapewear.

Mostly a good purchase

I bought this in size L/XL. I am 5'4" and about 220 lbs. I could have definitely sized down. It is comfortable but after a few wears it becomes a little loose so I do find it rolls down and/or the legs do ride up. It's comforting to wear and does prevent chaffing. The material is very opaque. I prefer the semi-sheer ones. Overall, mostly a good purchase. Would recommend but caution about sizing.

Worth Every Penny

I love the versatility of these shorts! While I do love the cooling shorts, they are too sheer to wear anywhere but underneath your clothes. These originals can be worn anywhere! I wear them around the house, running errands, under dresses, taking walks, doing yoga...anywhere. They are so comfy. I will get more wear out of these shorts than almost any other article of clothing I own.

I like them , very comfortable

They are great and get rid of the lines and do not bunch up, I’m not sure if I bought them too big , but I ordered a smaller size and will see how it works out .
