Thank you for looking. This is a silk blouse from Banana Republic. The size is US L, so I believe it corresponds to Japanese L to LL. - Width: 52cm - Length: 64cm - Sleeve length: 20cm (Please forgive any slight errors as these are amateur measurements) It is unused but has been stored at home, so please refrain from purchasing if you are concerned or seeking perfection. I accidentally cut off the tag that contained the spare button, so it is attached with tape (this has no effect on the blouse itself). Please excuse any wrinkles from folding during packaging.
