I want to first note that contrary to another reviewer, these are not 100% cotton, they are 100% polyester. If you're picky about materials and want natural fabrics, this isn't what you're looking for. That said, even though they aren't cotton, these have a thin and soft feel that doesn't feel cheap... or plasticky. Very on trend with the current balloon pant look, and I like that the fasteners at the bottoms can be made tighter or looser. The waist bungee is also functional, but it does slip, which isn't a big deal for me but could be a big deal if you need them cinched to keep them up. The light beige color is slightly sheer but white or nude undies aren't visible. I would say they are true to size; I am a size 2 and ordered M for a more baggy look, which I certainly got! They are a bit loose on the waist but I wear them on my hips and they are just fine. I'm sure a small would also be fine, just not sure they would be long enough for me at 5'6" with long legs.
