nobody under the age of 50 or not coaching a team should be wearing any polo shirt to a sporting event other than golf or tennis. Proper gameday attire is either a jersey (go to an NFL game or hell any pro sporting event and you won't go 5 steps without seeing somebody in a jersey) or a T-shirt/sweatshirt/hoodie/jacket with school colors and/or logos. Women get a pass but still need to wear something that incorporates school colors.
