The dress worn on occasions of ceremony. If a man has no special costume, his full dress is a suit of black, open waiscoat, swallowtailed coat, white neckcloth, and patent-leather boots or half-boots. Academicals are worn in the Universities and on official occasions; and full military dress is worn when an officer is on duty, at court, and at official fêtes, but otherwise, evening dress suffices.
