Brooks Brother men’s coat no size, see description

Brooks Brothers coat. See pictures for images. Does not have a size tag. Measures 49 in. from the neck to bottom and 35 in. from underarm to bottom. It measures 25 in. across front at bottom of underarm. The sleeves measure 18.5 in. along seam from underarm to edge. As seen in pictures, there are a few small stains, some loose threading, and a missing button on belt. That being said, with a little TLC, this piece has years left. Has nice zipped in lining and lots of details. Message for more.
