This is a knit tight skirt with a soft, marshmallow-like touch. It has a slit in the back. The color is black! I chose size M, but it's not indicated on the label, so I think it's S-M. It's stretchy. Here are the measurements, taken by a non-professional: Waist: Approximately 30cm Length: Approximately 59cm Hem width: Approximately 36cm Slit length: Approximately 15cm Thank you for considering this item.
