Maybe you were a Power Ranger when you were a kid or last year you totally rocked an awesome Katy Perry wig and candy-covered outfit.

Olivia Holt dressed up as a zombie cheerleader for her Disney XD show Kickin' It, but when M asked her what the best costume she ever wore was, she had a different answer. "I was pretty much every single princess. I was Belle, I was Cinderella, I was Sleeping Beauty. Those were my favorite!" Olivia exclusively tells M. "I love dressing up as a princess. This year I want to be Rapunzel, the next princess! I've been working on growing out my hair!"
