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).

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.

Life-changing! Seriously!

Absolutely love this product. Took your advice and go 'commando' and oh man - comfort, decency, and easy to look after. I've bought bucketloads already and if you get some more colours underway, I'll get bucket loads more. Who knew undie/shorts could be so addictive??


can't get along without these now...Love them

Thanks for the love, Mary!

Very comfortable and lives up to assertions. Will definitely order more.

We love to keep you comfortable, Raelene!
My new love affair!

I am now the proud owner of a pair of Ultra High Rise Cooling slip shorts. They are heavenly! I wore them to a formal function in 30 degree (Celcius) heat and they kept me cool and dry for over 12 hours! They felt like a silky second skin and are incredibly comfortable - no more hold-you-in-so-you-can-barely-breathe anti chafing wear for this gal! The size I ordered was 3XL/4XL and although they looked alarming small out of the packet, they stretch in all directions and went on beautifully. I've recommended them to several friends because I love them so much. And in this warm (Australian) weather, I'll definitely be inclined to wear dresses now that I have this secret weapon.
Thank you Thigh Society!

Thanks for recommending us, Jennifer! We're thigh-rilled to be your new love affair.
