The material tag on this shirt is missing, otherwise in very good used condition. Assuming it is made of polyester by the feel and since other similar express shirts are made of polyester. Bold but subtle in color with the white, gray, and black snake skin pattern all over. Lightweight, perfect for all seasons and a good casual or business shirt. Good statement piece for the office or dress it up for a night out. The sleeves can be rolled up and it is semi sheer and would recommend wearing something underneath if going for a business look. Fits into bold, loud, and edgy vibes. Semi relaxed fit. Measurements (approximate, when laid flat): Length: 27 in. Armpit to armpit: 21 in. Underarm: 19.5 in.
