Duofold Long Sleeve T-shirt This is a vintage item, and the tags are no longer visible, so the material is unknown, but it's very comfortable to wear. It's a well-known brand, famous for its 2-layer construction, but this one is thin. However, the comfortable and pleasant material is unique to the brand. It shows signs of wear, but in my subjective opinion, there are no major damages or holes. Please ask if you have any questions. Length: 65cm, Width: 47cm (approximate measurements) This piece can be worn as an inner layer, on its own, or even as loungewear. For those who understand vintage clothing, thank you for your consideration.
