Leggings and shorts lengths

Inseam is measured on the finished garment from the crotch seam to the hem. It's the same in every size, so you choose your size and your length separately.

Style Short Regular Tall
High Waist, Pocket, Mid-Rise, Sculpt and No-Front-Seam leggings 23" 25" 28"
Bootcut leggings 27" 29.5" 32"
Capri leggings 17"
High Waist and Pocket shorts 3" 5"

Which length for your height

A guide to where the hem lands, barefoot. Full length sits at the ankle; 7/8 sits just above it.

Your height Leggings (23" / 25" / 28") Bootcut
Up to 5'1" Short 23" for full length Short 27"
5'2"–5'4" Regular 25" for full length, or Short 23" as a 7/8 Regular 29.5"
5'5" Tall 28" for full length, or Regular 25" as a 7/8 Regular 29.5"
5'6"–5'9" Tall 28" for full length, or Regular 25" as a 7/8 Tall 32"
5'10" and up Tall 28" sits just above the ankle Tall 32"

Capri 17" is a mid-calf crop on most heights. Between two lengths? The longer one gathers slightly at the ankle; the shorter one sits as a 7/8.

How to choose your size

Most styles run true to size. PureFlex and Pure are garment dyed and pre-shrunk, so choose the size you normally wear.

If you're between sizes, please size up for the best fit.

Need a different length? Change the inseam, not the size. Leggings come in three inseams and shorts in two, so a shorter inseam at your true size will fit better than a smaller size.

Shorts: check the measurements at your hip rather than the size you usually wear in shorts.

Bras and tops: your usual size for a secure fit, or size up if you prefer less compression.

Pure Lightweight Joggers: these fit closer than the name suggests. If you want a relaxed fit, size up.

Texas-Grown and EcoLuxe styles: use the measurements on the chart above.

Still deciding between two sizes? Email hello@purakai.com and we will help.

How to measure

Bust: around the fullest part of your chest, with the tape flat but not tight.

Waist: around your natural waist, where you usually wear your pants. Relax and leave about 1/4 inch of slack.

Hips: around the widest part of your hips and seat, usually about 2 inches below your hip bones.

Inside leg: from your crotch straight down to where you want the hem, barefoot. Compare it with the inseams above.

Initially, I was concerned that maybe these leggings would slide down. They stay in place and are very comfortable! The feel is very soft and I can move easily with everything staying in place. Great quality and customer service!

I'm 5 feet tall and weigh 112lbs. These leggings aren't too long and don't look weird when I hike up the fabric a bit. I love the Tidal Teal color!

I bought these as a layer of warmth beneath ski pants. They hug nice and tight and are breathable. The 2x fits my 5-foot-6, 200 lb frame.

I love these leggings! I bought 3 more pairs after trying the first one! I literally wear leggings almost everyday and wanted to try a cotton version and even though these are expensive, they are way worth the money! I stay up, the tummy support is amazing, they keep me warmer but not too warm! Love them!

PureFlex Organic Cotton High Waist Leggings

Love these so much! I’ve tried so many natural material leggings and these are the only ones that I’ve liked… especially love the wide flat waistband that doesn’t dig in at all! And love the length options too. These are the best!!

PureFlex Organic Cotton High Waist Leggings

Fits great! I’ve tried many cotton leggings and these are the best. They stay put and don’t sag or lose their shape during the day

PureFlex Organic Cotton High Waist Leggings

These look so high waisted online but in person, they look great. At 5’1” and 128, I have thicker legs and butt and a small waist. This medium was perfect and feels good on. Not too tight or loose and the waist height looks great.

PureFlex Organic Cotton High Waist Leggings

These leggings are perfect for me. They feel supportive and soft, and they fit perfectly. I love that they come in various lengths! I'm 5'2" weigh 130, so the shortest inseam in size medium is just right

PureFlex Organic Cotton High Waist Leggings

These leggings are the best natural fiber leggings I have ever bought, hands down best clothing purchase I’ve made this year. They stay up during rigorous activity, they aren’t too see through, and they are soft as heck. Highly recommend and will be buying in more colors.

PureFlex Organic Cotton High Waist Leggings

I ordered a small (usual size) and medium, and found the medium more comfortable. Hopefully they don't stretch out over time. These are moderately thick and decently soft (I hope they will get softer with wear). Being able to choose your length is great! The thick seam above the pelvis and extremely high waist are a bit awkward but not dealbreakers. It is great to find a brand of mostly cotton leggings that seem good quality. The only issue was shipment time: I ordered these on 9/22 and they arrived 11/2, which was excessive.

PureFlex Organic Cotton High Waist Leggings

I bought these as well as the pocket leggings. This is my first order with PuraKai. I am extremely impressed and very pleased! These are exactly what I was hoping for. The quality and the fit are both outstanding. I like that with these leggings (the non-pocket ones) the seam is on the inner side of the leg, which looks nicer when worn with a skirt, and I like that the pocket leggings have, well, pockets! I will be living in these leggings all winter. Five stars, easy. It's hard to find quality clothing these days, so again, I'm just very impressed. Well done.

Customer video review of PureFlex Organic Cotton High Waist Leggings

I am obsessed with these leggings! The fit is fabulous! The rise is a perfect height, the wide waistband doesn’t dig in, the whole thing is compressive, the cotton is thick - the right thickness - enough to be compressive but still comfortable, and good quality. I think they are the best organic cotton legging on the market - and I have ordered and sent back several!! I am 5’4”, waist 29”, widest part of hips and booty 39” my inseam to the floor is 29”, and I order XS in regular length for compressive feel (in this video). I have ordered small for a more relaxed comfy lounge fit. Also their customer service is excellent and return/exchange policy has helped me to get exactly what I want and need!! Great company!!

Customer video review of PureFlex Organic Cotton High Waist Leggings

I finally found organic cotton leggings that I LOVE! I've tried Mate and Pact and nothing fits tight and feels as good as my Purakai leggings and top. I'll definitely be buying more colors and styles.

PureFlex Organic Cotton High Waist Leggings

PureFlex Organic Cotton High Waist Leggings

Second pair of Pura Kai leggings and I think I will be adding more to my collection! Already purchased shorts after receiving these. Slowly transitioning to natural fiber leggings and Pura Kai has made it super easy. The 23" length are perfect for my 5'2 frame and love the high rise waist band and feel.

PureFlex Organic Cotton High Waist Leggings

Amazing product!!! They slide down a little but you’ll be hard pressed to find a non-toxic brand that doesn’t. I am so happy with these, they feel amazing and are true to size.

PureFlex Organic Cotton High Waist Leggings

These are my favorite tights. I have every color and want more. The fit is perfect, I am 5’9” tall and they are perfect length.. love love love them

PureFlex Organic Cotton High Waist Leggings

The XXL 25” long leggings fit perfectly! I am 5’3” tall and 160 lbs. I usually wear size 12 or large, but I required an XXL in these leggings. I love them. Very comfortable!

Customer video review of PureFlex Organic Cotton High Waist Leggings

I’m coming back to buy more pairs (and other products I also loved) - I love them so much. As you can see in my video, they’re not see-through at all. I genuinely am so grateful for well-made workout clothes made with non-toxic materials! Hear me when I say that I am very picky about fit and function when it comes to workout clothes and prior to paying attention to materials used, it took me a long time to find a brand I liked. When I switched to investing in non-toxic clothing I tried a few brands. This has been my favorite by far! Admittedly having worn these for running, there is some pilling on the inner thighs, but the fit, look, and non-toxic materials are worth so much more than worrying about that. That’s just to be expected with natural materials. Plus their customer service is amazing! It warmed my heart to have old school customer support. Invest in this brand, you won’t regret it!
