This is a C・O・L・Z・A plaid pleated skirt. It's a women's size M, but my sixth-grade daughter used to wear it. The fabric is thick, so it's perfect for fall and winter. The back has elastic, and there's a zipper on the left side. It looks like a skirt, but it has a culotte lining (see photo 4). There's some wear and tear, but no noticeable stains. *Shipping method may be changed to Yu-Pack Mercari.
