Do you mean dress up like a princess or get a job at Disney as a princess?
At Disneyland the have something called the bibbidi bobbidi boutique, where a fairy godmother and other princess actually dress you up as whatever character you choose, how much they charge depends on how much you wanna get dressed up. They can do everything from your make up, hair all the way to the dress and everything. My nieces got this done and they absolutely loved it!
You audition! But you never become a Disney princess! There's only one. 😉
