THERE are many firsts in the fourth installment of the Harry Potter series, and one of them is showing the main character grow up into a real teenage boy, with a real teenage crush.

The perfect occasion to mark this moment in Harry Potter’s life is of course through a dinner dance. At the Hogwarts School of Witchcraft and Wizardry, this is called the Yule Ball, an enchanted evening of formal dress, dancing and well, dates!
