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.

All Aussie Women Need This Product

Thigh Society have produced a product that 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.
Thank you so much 😄

Hi Cath, thanks for the 5-star review. It's nice to hear your new Cooling slip shorts are keeping you comfy and chafe-free in the Australian heat - even in a skirt, dress or trousers! The lightweight, moisture-wicking fabric provides a barely-there feeling, so we're happy you gave us a chance and we can’t wait for you to tell the rest of your friends and family.
Super comfortable

These are going to be great over this summer, they are light and comfortable to wear, and they stay put and don't ride up or down.

Hi Jeanette, thanks for the 5-star review. We're thigh-rilled you're finding your new Cooling slip shorts to be light and comfortable and that they're staying put. They will certainly come in handy as the weather warms up, although we're jealous over here in Canada!
I Love Them!!!

Best undershorts. So much better than other materials at keeping you cool and not riding up. Mine took a while to arrive in Australia and cost more than I would usually pay but the results are awsome and totally worth it!

Worth the money

The most comfortable light weight shorts I’ve ever owned. Highly recommend.
