Frequently Asked Questions

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 inflict tight belly pressure discomfort like shapewear. Instead, they’re a lightweight, breathable and extra gentle long underwear essential you’ll reach for through pregnancy and beyond.

They’re 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.

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.

Rave reviews

You’re making us blush.

"I wore these in 95 degree weather for 4 days in DC. I wore a dress everyday with ease. No chafing no sweaty butt no rolling! This really does what it says it does and I couldn't be more pleased with my purchase! I wash these out in the sink in my hotel room every night and they were dry by morning. I am a bigger Curvy Girl and these did the job! I'm obsessed"



"Love love love these shorts! I’ve been wearing bike shorts under dresses for as long as I can remember and have always had issues with them riding up and occasional sweaty butt lol. These are so breathable and this color is actually a great “nude” option for me."

Samantha Boerner


"No sweaty butt. I was hesitant about this purchase because of the price tag. I decided to give them a try, and I was very happy with the cooling ones. Also, no chafing when I walked. So that was a double"

Stacy Butler


"Wore my cooling shorts under a dress for a night out - walking through a botanical garden - with 75% humidity - my leg areas were the only part of my body not sweating and feeling sticky. Very, very lightweight so you don't even realize you have them on - just comfort.  Easy to wash and air dry"

Amanda Bitetto


"I now have 4 cooling pairs and love them. I live in Florida and wear them year round. No more sweaty buns!! They do not roll down on me and I almost forget I have them on.

Cindy Lefler


"5***** all the way. My daughter is a ICU nurse, and on her feet all night, and works up a good sweat!! She is not a big girl 5"6 160lb and gets what we call chub rub.. WELL this total stopped that !! She even wears under her dresses.. Don't be fooled by imitators.. I have tried everything for this poor girl, and now Daddy is a hero !!"

James Galati


"I am so happy with this product! I have always worn pants because skirts or dresses were never comfortable. I always had problems with chaffing and sweating. I purchased these and tested them out for the day. They are amazing! No chaffing, no sweating, they were so so comfortable. Will be buying a second pair and recommending them to friends and family in the future!"

Sarah Fournier


"I really love these shorts!  They are comfortable, very smooth and discreet under my skirt, and they keep the sweat from dripping down my legs.  Five stars!"

Alice Benham


Tried everything I could think of from powders to oils and bike shorts. But THIS is the best thing out there. It doesn't roll up, doesn't make me sweat and it's so easy to take on and off. Great product! Will buying more in future



"Wore for the first time on a hot and humid evening under a dress. Didn't even realize I had them on! No swishy sound, no bunching, no sweating and no lines. Would recommend!"

Jan J.


"These are amazing! They don’t budge. They don’t make you sweat. And they don’t cut off your circulation! I don’t know what kind of magic created these shorts but they’re a total miracle! Love them so much!"

Jocelyn Konidela


"I don’t know how these are so good, but they are! So thin, never sweaty, don’t roll down or ride up. Perfect."
