The waist is elastic, and there's no size label, so I'm assuming it's free size. It's new, without tags. It's reversible, white and black. Even on the black side, a check pattern seems to appear depending on how the light hits it. Color: White, Black Pattern: Check Season: Spring/Summer Stains, tears, odors, etc.: None For purchases made between 9/29 and 10/7, shipping will be on or after 10/8. Please be aware of this.
