This is a blouse purchased from Zara. It has only been tried on, so please refrain from purchasing if you are concerned. The size label has been cut off, so I don't remember the Zara size, but since I bought it, I think it's a Japanese size S to M. It's quite roomy. Please refer to the actual measurements below. Actual Measurements: Body width: 45cm Shoulder width: 34cm Length: 59cm Sleeve length (from center back): 68cm Please forgive any errors as these are amateur measurements. It is double-layered. I will fold it as small as possible for shipping. No returns. Transparency: Sheer
