Vintage Frostproof Wool Plaid Shirt

This is a vintage plaid shirt by Frostproof. IT is marked as being 80% wool and 20% nylon. I believe it is a women's shirt but may be wrong. It is marked as size 16 and is about 29 inches long and 23 inches pit to pit. It is missing the button on the left sleeve. Otherwise it is in nice shape.
