This is a beautiful long sleeved shirt/blouse jacket has a banded waist and mother of pearl buttons. Deep front and back yoke. This top is cut for comfort. Content and care labels removed but I believe this to be made of 100% rayon. It feels and moves like silk. In mint condition. Size petite large- extra large. Measurements: shoulder to shoulder 17”; armpit to armpit 22.5”; 20.5”; length from shoulder 23”.
