The size is size 11, and the color is navy. It's a 3-piece set with two jackets and a dress. The dress sleeves are chiffon fabric. The ribbon on the white jacket can be removed. I bought it at Shimamura last year or the year before. I wore another suit, so this one has been unused and stored at home. The price tag is still attached, but the product tag has come off... You can use the navy jacket for the graduation ceremony and the white jacket for the entrance ceremony☆
