This is a Brooks Brothers Oxford button-down polo collar shirt, made in the USA. It's a short-sleeved button-down shirt. The size is 15½. Based on the tag, I estimate it's from the 90s. Personally, I love the poly-cotton blend. Those who like 60s American traditional style might understand. Especially during this time of year, I wash them frequently, and while 100% cotton shirts wrinkle, poly-blend shirts generally don't require ironing, even if they aren't non-iron.
