Frequently Asked Questions

You really can’t go wrong with any of our sleep shorts; it just depends on what level of sheerness you’re comfortable with. The Cooling is our most see-through, followed by The Staple and The Cotton which are both semi-sheer: safe enough to answer the door, but you may want to wear a long tee if you’re making a late-night run to the corner store for a pint of ice cream.

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

Nope! Think of our shorties as the hardest working item of clothing in your closet from day to night and back again. Wear them under anything to keep you dry and covered, or skip the top layer and get right to lounging. No one will know except your laundry since you’ll want to wash and wear them over and over.

Rave reviews

You’re making us blush.

"These slip shorts solve the problem of my thighs sticking when I sleep hot, and they’re breathable enough they’re like wearing next to nothing. In short, much less menopausal sleep discomfort. Love ‘em!"

Carrie Richardson


"Great under pants: No line across the thigh. Like 2nd skin: no pressure or binding. Wearing around house or to sleep with T-shirt and under pants and skirts. Where have you been all my life??"

Janet Reagan


"These slip shorts are bombdigity! I love sleeping in them, so comfy. Excellent under jeans in winter. Can't wait to wear them in the summer. Whenever that decides to arrive lol. I have told so many women! Keep on saving thighs."

J Uchacz


"These fit great. I've been looking for something like these for years. I sleep hot and needed something to keep my legs from sticking together."



"These are like 2nd skin. I use them to sleep in, instead of shorts. I don’t sweat like I used to. Would be perfect to wear under a dress as well. So incredibly comfortable, absolutely love them"

Zoria Griffin


"These shorts are so soft and comfortable I could wear them from when I wake up to when I go to sleep – and maybe even to bed as PJs! They helped so much in the warm summer heat to avoid irritation while walking. These are a MUST BUY!"



"These are the best slip shorts ever! Soft, no seams to show through, great coverage without being tight or binding. Soft and comfortable enough to sleep in! Ordering other colors soon."

Elizabeth Turner


"I’m tossing out my Spanx! Thank you Thigh Society for your amazing slip shorts! I could literally sleep in these! It doesn’t bunch up or roll down my waist. It also doesn’t cut off circulation to my thighs! I bought two in beige. Now I need to get two more in black!"

Anna K


"These are so comfy... Not only under dresses, but just hanging out at home or as sleep shorts. I bought two pairs and will be buying more.  They're great!"

Jaime Fulsang


"Ordered 7 inch charcoal to sleep in.  They are super comfortable. Waist does not roll down and legs don't roll up."

Thigh High


"These slip shorts are great! Very comfortable, don't ride up or roll down and breathe really well. I've even worn them to sleep in and was comfy all night. I would highly recommend them and will definitely purchase more."
