Size is just a number.

Let's figure yours out

Fabric & Sizing Tips:

Hip measurements are more accurate than pant size: if you have a tape measure handy, make sure to measure over the largest part of your tush. No tape measure? Go with your smallest pant size. Our shorts are super stretchy and most women fit across 2 sizes, but the fit should be second-skin-snug.

Help! I fall in-between sizes. Do I size up or down?: We generally suggest sizing down (especially in Ultra High - Cooling and Originals). The only time you'd even consider sizing up as an in-betweenie is if you're th-eyeing the Regular Rise and your waist and hips measure about the same. 

Smoothing comfort: our everyway stretch fabric is a welcome alternative to tight and constricting shapewear. No wriggling or circus contortions needed to put them on or take them off. Hooray!

Note that our black garments can feel a tiny bit more snug than beige or cinnamon at first, but will mold to your body like a hug in no time flat.

My Thighs are thanking me!!!

I LOVE these cooling shorts, so light and silky. I got a pair for my sister too so she can enjoy wearing dresses again. Yay!!

Australian Women Wear Whatever You Want

Thigh Society cooling anti-chafing slip short does everything it claims. I live in Australia and it’s hot. I love wearing skirts and dresses to combat the heat. Unfortunately although I’m size 14/16 chafing had me googling my options. I thought more layers would be counterproductive, so how happy am I took a chance and gave them a try. They truly wick the moisture away and keep me feeling comfortable all day. I already have my daughter hooked. I think they’ll also work well under lightweight wide leg trousers, taking away that see through effect and moisture clinging issue.
I thank you and so do my thighs 🤣💜.
