I wore this once for the entrance ceremony. I've kept it in the closet for several years, but I'm selling it to declutter. This is a 23区 (23区 is a Japanese clothing brand) jacket and dress set that I purchased as a coordinated outfit. I believe the total cost was around 40,000 yen. The jacket is navy. It's a light and soft material. It's washable and stretchy. The dress has a textured fabric with a mosaic pattern of white, gray, and black. The sleeves are short. It's easy to wear a jacket over it. There is a thin gray lining throughout the dress, except for the sleeves' lining. It has a straight silhouette, so it's comfortable to wear without feeling constricted. It's a fabric and color scheme perfect for a refreshing spring. I think it will give off a high-quality and elegant atmosphere when you wear it. It can also be made more glamorous with a corsage or necklace. The patterned dress will be the accent, so I recommend a simple look with just earrings. I usually wear a size 13.
