Friday black tie dinners?
Black-tie dinners usually do involve a nice dress or suit for the men. The proper ball gown/tux is usually reserved for the Green Templeton College Ball (in June or July each year), but a nice cocktail dress, or nice dress/ suit to go to a restaurant usually does the trick. Basically it is only students that go to these dinners, so whatever you wear at Green Templeton will be fine!
