Le Collezioni Structure Vintage Wool Blend Shacket Mens Medium Brown Black Plaid

Shirt? Jacket? Why not both in one? Very cool vintage find. I believe this is from the 90s from the research I did but cannot definitively confirm.
I mentioned in the condition tab but I want to reiterate to CHECK MEASUREMENTS. It looks rather big for a size medium. When I came across this I wanted to keep it for myself. I'm a men's size small but figured a "European Medium" might work as a bit of a baggy fit style...... It didn't.
