Would my parents get mad if they saw me in a cheerleading uniform?

I'm a 16-year old boy, and I bought a cheerleading uniform to wear for Halloween last year. But lately I find myself putting it on and prancing around the house when no one else is home. If my parents came home unexpectedly early and saw me wearing it, what do you think they might do? Or how would they react? The idea is to avoid having them see me wearing it.
