Perhaps this is because of the negative associations with which the polo shirt is laden. It is often thought of in terms of a uniform — either literally, as in the required get-up of a pizza delivery man or elementary school student, or metaphorically, as the go-to garb for corporate drones and preppy fraternity brothers. The polo is further seen as the default of the sartorially lazy — something a guy dons when an event requires a shirt with a collar, and he can’t be bothered to even button up an Oxford.http://www.yunzhougarment.com/polo-shirt/
