This is an ethnic long skirt. It's made of a sheer material, but it has a knee-length lining inside, so you can wear it on its own. The size is unknown, but I think it's about a size M. The waist is elastic, so it's comfortable to wear. It's made of a smooth chiffon material, perfect for summer. There's a small snag that's not very noticeable. Some of the threads on the waist are frayed and coming undone. Please refrain from purchasing if you are sensitive to used items.
