This is a long shirt/tunic with a detachable collar. It can also be worn as a light jacket by opening the front buttons. Made of polyester, so it's wrinkle-resistant and doesn't require ironing. My child used to wear it, but they don't like it anymore, so I'm selling it. Please purchase only if you understand that this is a used item. Length: Approximately 86cm Width: Approximately 59cm Please note that there may be slight variations due to amateur measurements. (_ _) Color: White系 (White-based) Material: Polyester (synthetic fiber) Transparency: Sheer Season: Spring/Summer
