Ted Baker London tunic, unusual sleeves, embroidered, Ted Baker size 3 = US 8

Ted Baker sheer black tunic blouse with unusual long sleeves and laced neckline surrounded by embroidery. Note that Ted Baker size 3 equals U.S. size 8, according to their online size chart. Mannequin’s measurements are 34/26/36, with a B cup. The tunic is too large for her. No fiber/care tag. I think it’s silk or rayon, but I’m not sure. Excellent gently used condition. From a smoke free and pet free home.
