Black tight skirt made of stretch material, with a back zipper. - Color: Black - Design: Tight skirt - Zipper: Back zipper Thank you for viewing. This is a size 2 Theory skirt. I am selling it because it no longer fits. I think I wore it about 5 times. The waist is 37cm on one side, and the length is about 59cm, but because it's designed to be worn low-waisted, it will likely be knee-length.
