So these came in the mail (postal) in a small, concealable, opaque white bag, which was good because they were a gift for my loved one and I didn't want her to see. I purchased the OS (one size fits all). The material is very interesting, unlike anything I have seen before. Just before we were about to get busy, I pulled the stockings out. She put them on for me, but she was having a very difficult time keeping the tops (where the lace is) from rolling down her thighs. It's almost a design flaw or wrong material choice because there isn't enough elasticity or strength in the tops where the lace trim is. It wasn't that her thighs weren't big enough either because the leggings fit perfect around her legs, it's just that the material seems to curl/roll down from the tops even if you are a perfect fit in the OS size (she isn't a plus size by any means, very average, not tiny but solid thighs). It was fine though, we both didn't mind that aspect of the product. The wetlook is a big turn on for me, so it works. If you're into it, definitely consider these (if you don't mind the minor curling from the lace).
