A formal occasion to mark the end of school and moving onto college. Girls and Boys both pay a large amount of money to the organises, who then take this money and turn peoples dreams into reality. It usually includes large marquees, dj's, all decorated with fairy lights. Girls wear expensive dresses which keep them dignified and elegant. It is a night to remember and so most people tend to splash out. Boys wear suits or tuxes which ensure formal attire.
e.g. I am going to a prom at the end of my school year.
