I purchased this at a local vintage clothing store that carries items from overseas. It's a long-sleeved shirt from J.Crew. The material is cotton and silk. The color is dark, so it's not see-through, but it's a thin shirt with a nice feel against the skin. The pattern is an all-over bird print, similar to Liberty fabrics. The size is: width 43cm, shoulder width 38cm, length 63.5cm, sleeve length 56.5cm, sleeve width 30cm. Please allow for some slight variations. The label says "boy," but I think it's suitable for women with slender arms, based on the material and size. Thank you very much.
