I purchased this at Jun's shop. 100% polyester Size M Measurements (laid flat): Width approx. 50cm, Length approx. 55cm. It's a size M, but it has a relaxed fit. It's a pullover style, so it's easy to put on and take off. You can wear it on its own, or layer it with a turtleneck undershirt, etc. I wore it 2-3 times. It has been home-laundered. Thank you.
