This is a custom-made item from Matsuzakaya in Ginza. The material is unknown, but it is an extremely lightweight and supple high-quality fabric. The buttons also reflect the custom-made nature of the item. This item has been stored at home for a long time in my mother's wardrobe. There is no sign of wear on the collar or cuffs, but please refrain from purchasing if you are overly concerned about condition. It has a stylish, glossy paisley pattern. Measurements (laid flat): Shoulder width: 40cm Body width: 48cm Length: 94cm Sleeve length: 54cm
