Katy Perry sat down with People to share her thoughts on judging "American Idol," her tour fashion evolution, body positivity and more.
When discussing her tour and fashion evolution she says, "I like trying new things, I like experimenting musically sonically and with my style and trends change. You know, I like to start trends not necessarily follow them... I would say there's one costume maybe like every year that kind of like rises to the top and becomes a 'Halloween costume.' And that's when you know that you're like doing something is when people dress as you for Halloween."
