This is a JC Penney shirt. I purchased it at a used clothing store. The age is unknown, and there is no size label. Actual size (flat measurement): Shoulder width: 40cm Width: 45cm Sleeve length: 25cm Length: 73cm Please note that there may be some errors due to amateur measurements. As this is a used item, please refrain from purchasing if you are looking for something in new condition or if you are sensitive to such things.
