I bought this at an outlet store. The tag has been cut off, so the size and material are unknown. It's made of a wrinkle-resistant material, probably polyester. Likely a size M. Can be worn as a light jacket when the buttons are open. Five-sleeve length Puff sleeves No ironing needed Shoulder width: 40cm Body width: 52cm Length: 111cm Stains, tears, or odors: None Pattern: Floral Season: Spring/Summer Color: White系 (White-based)
