The size is 9AR. I wore it for my child's graduation and entrance ceremonies. I wore the jacket and skirt for the graduation ceremony, and the jacket and dress for the entrance ceremony, allowing for versatile wear. The dress alone can also be worn for parties, etc. The ribbon on the dress is removable. By attaching the parts in the 16th photo to the jacket, you can wear it without a blouse. Color: Black系 (Black-based) Stains, tears, odors, etc.: None
