The material is really soft and comfortable and not thin. I love that they aren’t see through! I got the xs I’m 5’7 and 115 and these are a great fitted pant without being tight. They actually go to my ankle which I love but if you’re maybe 5’5 or shorter I would do a petite unless you like long pants. The waist band is snug and snatches your tummy in a little which I think looks cute with the shirt tucked in. Great pants and I’ll definitely buy this brand of joggers again.
