Leggings stretchable NWOT

Brand new still in the plastic bag it came in. 95% polyester. 5 % spandex. One size fits all as per the ad I saw because of the stretchable material. I would say small to medium though. It looks blue in the picture, but it is black and grey. In the first picture it looks as if there are pockets and buttons, but that is not true. It is just the print.
