This is a ceremony suit set I purchased from Ryu Ryu several years ago. I threw away the corsage, so it's the four-piece set: tweed jacket, jacket, dress, and pants. The color is navy, and the size is 9. I believe I wore it once each for the graduation ceremony, entrance ceremony, and wedding. I think it can be used for various ceremonies other than graduation, entrance ceremonies, and weddings, such as Shichi-Go-San (Children's Day).
