I purchased this at a used shop, so I don't have any certificates of authenticity. Please check the tags for confirmation. It's a reversible wrap skirt, with a beige side and a Burberry tartan check side. The waist fabric doesn't stretch much, so it fits quite tightly, but I think the size is SS to S. I (160cm, 48kg) could wear it. The length covers the knees, but it might not be considered a long skirt. I liked it because it was elegant. Includes shipping.
