This is a 3-piece set consisting of a dress, a jacket, and a skirt. I purchased it the year before last. You can wear it in various situations by changing the combinations. The size is size 9, which is equivalent to a size M. The dress and jacket were worn only once for a short time at an entrance ceremony. There are no noticeable scratches or stains, and they are in a clean condition. The skirt is unused. Please understand that this is a used item. Shipping will be done compactly.
