Very gently used. Lightweight. In the back, it is 23 inches long. It is 21.5 inches wide from underarm to underarm. There are slits on each side that measure 3.5 inches each.  60% cotton & 40% polyester. The material around the last button on the bottom is beginning to fray as shown in the last picture. Comes from a smoke free and pet free home. I re-use mailing envelopes and packing material in order to keep my prices low.
