Fit perfect!

I’m 5’3 140lbs & ordered a medium. They fit perfect. Underwear stays in place as well as the pant. They are very comfortable for working out or relaxing in. They are thick enough so no lumps, bumps or lines show. They wash well. I highly recommend. Only complaint is I wish there was a pocket for my phone! Would love to see more available product. Everything was out in my size.

Thanks so much Jenny! We're so so glad you're enjoying your new leggings. Thank you for the feedback as well. We're working on some new styles over here we think you'll be excited about! :)

super comfy - review from my girlfriend

The fabric and fit are everything you would want from leggings. They're exceedingly comfortable, sleek and smooth feeling (gives your body great shape and support throughout the day). The cut of the built in underwear was fabulous as well- no readjusting and everything stays where you want it to. Overall, awesome quality for the price and would recommend to those who want to look put together on the go!

PS

These are period friendly leggings. Ladies, you know why!!

Hi Nickolay! We're so happy the leggings you gifted your girlfriend were a hit! Please thank her for the kind words as well and the feedback. SO happy to hear she loves them and their functionality has been a welcome addition to her lifestyle!

Keep it smooth

We don't use side seams or a vertical back seam in our undies. We bring you our ingenious thong and comfy classic fit underwear built right into styles made to fit you and your life. We will never try to sell you a typical pair of tights.
