Great quality and very comfy

I’ve been on the hunt for some good quality, cotton briefs. I’m prone to BV and other issues down there. I appreciate that Knickey accepts old underwear as trade-in for points, which is how I got 15% off my order. The quality, stitching, and fit is superb. I’ll be making more trade-ins and purchases in the future! Thanks Knickey :)

An amazing basic

So comfortable, soft and has held up so well (been about a year and a half). Definitely recommend!

Best undies

The knickey briefs will replace everything I currently own. They are comfortable, give excellent coverage and are easy to wash.

Pretty and oh so comfy!

These undies are a perfect fit on me, snug and yet so light. I love the color, it’s as rich and pretty as it appears on the site. I love them!

A Dreammmmmmm

These are super duper cozy to wear. The hi-cut leg gives a special kind of oomph on this simple style. These don't cut or dig into me at all and are truly so comfortable and flattering!!
