Size: Jacket, Dress: 1 Skirt: 2 *Blouse not included. Although the sizes are different, they were purchased at the same time and I believe they are equivalent to a size M. However, I have measured them laid flat, so please refer to the photos. The color can be used as formal wear. It can be worn for ceremonies such as graduation and entrance ceremonies, and each piece can also be coordinated separately with other clothes. Each item has only been used about 5 times, so there are no noticeable scratches or stains. However, as they are used items, please forgive any oversights. Please consider purchasing if you understand that there may be creases due to shipping.
