This is the Original Brooks Brothers Vintage Fun Shirt! From the days that the sport shirts had sized sleeves. The 14.5 neck came with a 43" sleeve. It's 100% cotton and made in the USA. It's a man's shirt, but I wore it over jeans. It's classic, and you'll never find another like it. The inside neck has my last name, very lightly from the cleaners, unfortunately, but it doesn't show.
