May run a little small. I wear a large, my sport coat is a 44L I'm tall, no belly. Ordered the large knowing the arms would be a little short, jacket did not fit lacked 4" of coming together at button, returned. (Amazon is easy & great to do business with) Ordered the XL that was a keeper. I like the lighter material for warmer weather, evenings, etc., the color was accurate. Just what I was looking for.
