I have a Disney audition next week and need some help...?

Dress sensibly, but with your personality showing too; perhaps a simple ensemble with a daring piece of jewelry. They will probably ask you about previous work you've done that may give you a leg up against other teens. Just be prepared to answer any question they ask honestly. I cannot stress enough how much of an impact a cheery attitude will make. They want someone who is talented and a delight to have on set, so don't act like you're too cool to care. And of course, don't forget to smile!
