The Friday evening dance is best dress (the Tuesday dance is casual dress)
Best dress for young men:
A collared shirt (white or coloured) that buttons down the front should be worn. Less formal ties are considered appropriate for the Friday night dance. Shirttails should always be tucked inside the trousers. Young men should wear smart or suit trousers with dress shoes.
Best dress for young women:
Smart trousers, dresses, and skirts which are knee–length or longer are appropriate best–dress clothing. Slits in dresses and skirts must not extend above the knee. It is not necessary to wear a ‘prom-style’ dress.
Beach or athletic footwear is not appropriate for the best dress dance for young men or young women.
