Isn’t it silly to suppose that the way students dress would have an effect on their education? Suppose you were in Court for something important, and the judge decided that a jogging suit would be more comfy than judicial robes. Would that be disturbing for any other reason than it being non-traditional? Costume is a way of reinforcing mindset. A judge in robes is reminded of his judicial responsibility. Students in uniform are similarly reminded of their roles as students.
