When I was young my dad was in the Marine Corps. When he took us on base, people walking by would snap off a crisp salute because of his dress. He carried a certain rank and with that rank came an expected behavior to the person who possessed that rank.
In our church, when the Bishop walks in a meeting, there is a certain respect accorded him because of his position. He dresses the part, 2 or 3 piece suit, a white shirt, and normally with a conservative tie.
