Hugo Boss Grey Pencil Skirt 99% wool size 0 but fits more like a 2

Like new grey pencil skirt by Hugo Boss. Retails for $150. 99% wool with polyester lining. ZIpper is on the side (invisible). Skirt measures 22 inches from top to bottom. Size says a US 0, but this definitely fits like a size 2. Great for the corporate, office look. Please don't mind the wrinkles in the photo and note that the stock photo has a slightly different waist. See other photos for accuracy.
