It's made of soft polyester material. Because the design of the fluffy collar and sleeves is not apparent when hung on a hanger, I've photographed it laid flat on the floor. It's labeled as size S, but it feels like a size M. It's quite loose-fitting, so I've labeled it as free size. The material is smooth, and the design is relaxed, so please check the width and length in images 4 and 5, where I've used a measuring tape. (Please excuse any measurement errors.) #Formal #Casual #Office
