The color is light gray, and the waist has elastic all the way around. There is no lining, but it's not see-through. The photos of the item being worn appear lighter than the actual color. Size M Measured flat: width 43cm, waist 33cm, length 112cm I've worn it 2 or 3 times, and there's a little bit of fuzziness characteristic of the material, but no noticeable stains.
