Frequently Asked Questions


What is thigh chafing, anyway?

Thigh chafing/chaffing is caused by sweat and friction when one’s inner thighs rub together painfully (skin on skin or against clothing), often leading to a fiery, burning rash. This irritation makes it very uncomfortable to wear dresses, skirts or pants - especially in hot and humid weather. People with bodies of all shapes and sizes can get chafing - sometimes endearingly called "chub rub" - but that's not meant to imply that only bigger people chafe. Thigh chafing doesn't discriminate based on age, size, weight, height, skin colour, ethnicity or gender. Contrary to popular belief, it has more to do with anatomy, friction + skin sensitivity. Mind. Blown?! Let's repeat that again for any non-believers: thigh chafing is NOT about weight. Anyone who has thighs is fair game for chafing under the right conditions. Period.  

So this really isn't shapewear?

Nope, not shapewear! Thigh Society's soft and stretchy fabric provides comfort and coverage with some very light smoothing, but definitely doesn't feel like shapewear, nylons, hosiery, bike shorts, or compression pants. Some of our customers say the material feels like cotton, others liken it to a high quality, lightweight legging. Unlike shapewear, Thigh Society was designed to be worn all day, every day. You can even sleep in 'em (fo real). 

Besides chafe-provention, what else is Thigh Society for?
We're glad you asked! You can think of Thigh Society as your secret weapon:
Is Thigh Society for all seasons?

Spring, summer, fall or winter – Thigh Society can be worn all year round. Put 'em on under a wrap skirt in the fresh Spring breeze, under a Summer dress on a swelteringly hot day, under or over tights/pantyhose in the Autumn/Fall to extend the life of your hosiery, or for an extra layer of warmth in Winter. Our slip shorts also make fast friends with any pair of bottoms with a dropped inseam (jumpers, scrubs, chef's whites, harem pants...) where your thighs may be touching and/or under sheer fabrics. And don’t forget to bring them with you on your tropical holidays – they'll be your new BFFs!

How do they work to remove sweat?

Thigh Society is made a of a luxurious moisture wicking microfiber that naturally wicks moisture, and gets an extra boost with our ventilated mesh inner thigh panel made with Sorbtek® yarn. This fabric uses an advanced "Catch, Move, and Release” system to catch moisture quickly, move it off your skin and then release it for evaporation 4x faster than other fabrics. Other fabrics only absorb moisture after prolonged contact, but Sorbtek® draws sweat off of skin right away, leaving no time for discomfort and keeping you dry and comfortable. 

Don't be fooled by other brands of anti-chafing shorts that promote the use of cotton in the inner thigh panel. Cotton, while breathable, is notorious for trapping moisture and keeping it there...which means an higher chance of getting a nasty thigh rash. 


We've been saving thighs for a LONG time

When Marnie first started the company in 2009, there were barely any options to prevent thigh chaffing unless you wanted to wear men's boxer briefs, bike shorts or cut your leggings, tights and pantyhose. It's sooooo exciting to see new options from creams to lacy bands and shorts, since there are as many varieties of chafing as there are bodies out there (right?!), and what may work for one person might not for another.

Our philosophy has remained the same since Day 1: offer a great fitting, high quality, comfortable, breathable and sweat reducing knicker that you'll actually want to reach for when getting dressed.

Our slip shorts will last you a LONG time - many customers still have the original pair they bought 8 years ago - and they won't let you down in your time of need. We don't cut corners (pun intended!) with our sizing, which is how we can ensure a perfect fit. Still need more convincing? More fabulousness  here.

How do I know these are high quality without seeing them first?

Have you ever bought other brands of so-called anti-chafing shorts and put them on, only to find they felt too tight? Or when you bend over, you give the world a spontaneous show? Or when they lose their shape after being worn and don't bounce back? Or when the waistband and leg seam start unravelling after the first wash, also riding up and giving you muffin top? Or when they're labelled as "one size fits all" but they really don't fit *anyone* (not well, anyway)?! Those shorts are all low quality. At our North American factory, we only use the best yarns and thread to ensure a long-lasting, high performing finished garment. Our high quality comes from the fabric we use, our signature fit and construction- and we’ve spent 8 years obsessing over each. 

Wouldn't bike shorts be a cheaper alternative? 

Cheaper, maybe - but our panty shorts have several added advantages over bike shorts:

  1. They are super soft and lightweight. Our beautiful fabric feels soft and luxurious against your skin, and we bet you'll forget you're even wearing them.
  2. They are virtually seam free. Bike shorts often have thread seams right down the middle of your most sensitive inner thigh area, along with annoying front and back seams - increasing the likelihood of chafing. We've removed those seams and added one large inner thigh panel that eliminates friction and keeps you dry.
  3. You get 2 for 1 with Thigh Society since they are meant to be worn as underwear - there's no need to double up on extra layers.
  4. The unparalleled stretch and recovery of our fabric will rival any biking short you've ever put on.
  5. There are no elastics so you don't have to worry about a waistband that digs in or causes muffin top.
We are first & foremost a body positive brand

At Thigh Society, we're on a mission to help women everywhere dress confidently, comfortably and free of body shame (follow us anywhere on social media and you'll see what we mean!). We do that by providing a practical solution to the perfectly normal thigh chafing problem that many women have, but may be too embarrassed to talk about. We want to end the stigma surrounding thigh chafing once and for all!

Shapewear brands have tried to convince us that we need to transform our bodies by squeezing into gut-wrenching undergarments, but we believe that confidence emerges from being comfortable from the inside out. Our anti-chafing crusade is about embracing that philosophy and enjoying a chafe-free existence in the process.


What material is Thigh Society made of? 

Our material is made up of 90% nylon microfiber, 10% spandex with a Sorbtek® thigh panel (gusset). Starting with the fiber that gives the shorts their amazing stretch - that 10% spandex is a yarn that helps your shorts mould to your curves and bounce back to their original form. The other component that makes up the bulk of the panty shorts is nylon microfiber. Nylon microfiber is a strong fiber known for its silky-soft and lustrous feel, plus it wicks away moisture like a champ, and also stretches. Lastly, breathable Sorbtek® has been added for extra moisture-wicking reinforcement in the most chafe-prone area: the inner thigh panel. Sorbtek® catches moisture, moves it away and releases it for quick evaporation to keep you cool, dry and comfortable - unlike, say, cotton - which traps moisture and keeps it there, priming your skin for a nasty rash.  

Granny said "only wear cotton panties"

Granny had a lot of great advice - but fabric technology has come a long way since she was buying undies. Thigh Society’s high quality microfiber fabric is a breathable, lighweight, soft and skin friendly nylon/spandex blend. Plus, the Sorbtek® fibers quickly absorb and pull sweat away from the skin surface waaaay faster than cotton, keeping your lady bits happy and dry.

Is Thigh Society machine washable?

Yup - they're super easy to care for. You can wash them in cold water and tumble dry on a low to medium heat setting, which will allow the fabric to regain its original, great fitting shape. 

How often should I wash them?

Even though Thigh Society shorts have amazing recovery and won't stretch out during the day, we recommend that you wash them after every time you've worn them for the day (even if you've worn them with underwear) to ensure that the fabric regains its original, great fitting shape. 

Will the fabric cling to clothes?

Our slip shorts shouldn't cling to your outer clothing, but sometimes very dry conditions can cause static. In that case, all you need to do is spray a bit of static guard and you're good to go. Putting some moisturizer on your legs first or wetting your hands and smoothing out the fabric can also help combat the dryness that causes static. 

Will the fabric make noise when I walk?

We designed our fabric to be different from tights and pantyhose, which usually come with a very loud "swooshing" sound when you walk. Our fabric is made to feel more like cotton and gets even softer in the wash. That said, our nylon fabric keeps you dry by absorbing less moisture compared to cotton. Scientifically speaking, more moisture at the friction point between your thighs would result in reduced noise, but then you wouldn't be as comfortable. It's a bit of a trade off and we're always looking at new options.


What's the diff between the mid, high and ultra high rise styles?

All styles are made of the same lightweight, breathable and moisture-wicking microfiber fabric. The Ultra High Rise has a longer leg inseam (9") compared to the Mid & High Rise (7.5") and the Ultra High Rise comes up way above your natural waist with *a lot* more tummy coverage. Our Ultra High Rise style has more generous front, back and leg coverage than either the Mid or High Rise, so if you want maximum protection, and prefer really high waisted underwear, that's your pick. If you're short but like your tummy pretty covered, we suggest the High Rise. 

Will I have to pull and tug to get 'em on?

Nope! Thigh Society is super easy to put on and take off, since the material is very stretchy. Unlike shapewear, it won't make you feel like a sausage in too-tight casing (the horror!)

Will the waistband roll or legs ride up?

We sure hope not - then we'd be out of business! No muffin top and no digging in at the legs. Our designers and knitting technicians have decades of experience developing seamless intimates and high performance clothing to ensure a proper fit. Plus, we don't use a "one-size-fits-all" approach to sizing.  We don't know about you, but those pieces *never* fit us properly. Still not convinced? Check out some of our press and blogger reviews here, and be sure to order the right size

Will I get V.P.L.?

V.P.L. is short for Visible Panty Lines and happens when the outline of one’s undergarments (usually around the butt area) is visible through clothing. With our virtually seamless and elastic-free design, and combination of flat seam and seamless construction - it means you won’t have any V.P.L. High five!

What is camel toe and will I get it?

According to Wikipedia, camel toe is “a slang term that refers to the outline of a human female's labia majora, as seen through tightly fitting clothes. Due to a combination of anatomical factors and the snugness of the fabric covering it, the crotch and pudendal cleft may take on a resemblance to the forefoot of a camel.”

Ick. Rest assured that we have a “no camel toe guarantee” with Thigh Society’s seamless gusset area, where your lady bits can rest comfortably without any annoying central seams.


I'm pregnant - can I wear Thigh Society?

While our current Thigh Society style isn't specifically designed for maternity, the super stretchy fabric can accommodate a growing belly and will protect your inner thighs from chafing, which can happen with pregnancy weight gain. Many moms-to-be have worn their Thigh Society for up to the first 5-6 months, but it depends on how you carry.

I get hot flashes - can you help?

Yes! If you're a menopausal woman who gets hot flashes, let our inner thigh gusset technology do the work to wick sweat away 4 times faster than other competitive fabrics, keeping you and dry and comfortable.

Can I wear Thigh Society to sleep?

100%! They're super comfortable to sleep in, and will protect your delicate parts, especially if there’s no air conditioning. The breathable fabric ensures dryness and softness all day and night.

If Thigh Society is made in Canada, why do you charge in $US?
We've proudly been providing our best-selling slip shorts for the past 8 years and counting, made in an ethical factory with responsible labour and health & safety practices. During this time, our anti-chafing crusade has expanded internationally, and although growth is a great sign of success, higher costs of materials (sourced in the US) and global operations have followed. We've worked hard to maintain our pricing over the years but in order to fight chafing and keep women all over the world feeling fabulous, we made the decision to charge in US dollars.




We offer sizing to fit gorgeous bodies of many shapes and sizes.

Our four way stretchy, breathable microfiber hugs your curves to give a smoothing effect without feeling squished like in shapewear.

If you're in between sizes, we recommend sizing up . Size is just a number and we want you to feel great! Our Ultra High Rise style has more generous front, back and leg coverage than either the Mid or High Rise, so if you want maximum protection, and prefer really high waisted underwear, that's your pick.

Our material is *super stretchy*, which makes it tough for us to give recommendations based on hip or waist measurements. Most women will fit in at least 2 of our sizes, but it's best to pick the size that is closest to what you normally wear.

If you're not sure, have a look at some brands of skirts, dresses or pant bottoms that you've bought recently, as a guideline.  

And if you're *still* not sure, email us at:

Due to health reasons, we are unfortunately not able to accept any exchanges or returns of underwear.
