Boyshort

I have narrow hips and these were the perfect fit. Not too high or low. I am 5'3, 130 lbs and ordered a size small.

My favourite!!

I’ve been wearing Knix undies for about 6 months now and I love them. They mold to your body after a few wears which make them so comfortable and perfect. I like these so much that I’ve repurchased many more. They are the best!!
