Love these leggings! Not see-through at all--they are nice and thick. The wide waistband is perfect for my four-baby belly...holds everything in. I ordered my usual size (Small) and it's a perfect fit. I am 5'11", 135 lbs and these come to my ankles, which is hard for me to find!
I was hoping to find a pair of leggings that were opaque and fit well. I wanted something that I could wear without a long shirt or tunic, just as pants bc leggings are pants in my opinion, not tights. Anyway, they fit weird in the crotch and were a bit sheer, I tried xs and s which is my normal size. Nordstrom has excellent customer service and return policy so I gave them 3 stars.
This is the first time I tried these, but I love them. Great quality. Not too thin and I love the wide waist band. So comfortable that you will want to live in them. I got black so I can wear with everything. I am a size 10/12 and the large is perfect.
