These leggings are super stretchy and a nice, thick material! They do run BIG- they are a size large, but fit more like an extra large. I was not aware of this when I bought them and they felt too big on me. If you normally wear a size extra large, then these would fit nice on you. The color is in between a dark grey/dark blue. Comes from a smoke free, pet free home. Please let me know if you have any questions! Thank you! **I am always willing to accept reasonable offers, but please be aware that I need to make a profit, too. I'm not going to sell and take the time to package and ship an item that I'm only going to make 50 cents in earnings. Please be mindful of this.**
