It says 120-60, but it feels a little small. I think it's probably around 100. I've placed a 90-size vest (green) next to it, so I hope you can use it as a reference for the size. If you would like me to take measurements, please let me know. 60% acrylic 40% wool It has been used, but the item itself is sturdy, so there should be no problem with wearing it. I think there are individual differences in how things are perceived, so please only purchase if you understand that it is a used item.
