I was looking for a pair of white leggings to wear under tunics & dresses that weren't see-thru and cheap-looking, and these are great! They do run small and I recommend sizing up a size or two! According to the size chart, I should wear an XS  (5'5, 115 lbs) but I couldn't even get them over my thighs. The size Small fits but still very snug around the waist. I am considering trying a Medium just to see the difference. But, I love the look and feel of them! Made with nice thick & stretchy material.
