Cadets wear the Class A coat on special occasions such as the Military Ball, and sometimes on Fridays for Dress to Impress. The Class B is worn with or without a black necktie issued with it. The tie is worn if the Class A is worn over the Class B. If the Class A is worn over a white dress shirt for something like the Military Ball, then a black bowtie is worn.
