Please read the self-introduction section. Shimamura juo Can be used as a style, vest, or付け襟 (detachable collar) ☺︎ The sides have ribbon ties for adjustment. The back has two buttons. I bought it because I thought it was cute, but it didn't match my existing clothes, so I ended up not using it and just storing it. Therefore, it is a beautiful item, only tried on. For those who understand used items, please purchase. It will be folded small and shipped compactly. Shimamura Birthday juo tete a tete mamaraku
