My school is an all boys one, but you just take a girl from outside the school to the formal. Of course, you're allowed to just go alone if you want to. If a school didn't allow you to take people from outside the school, thats like.. incest or something heh ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
