Did Katy's theatrical and creative performances/costumes influence the industry?
in 2008 BEFORE anyone else dressed weirdly:
There's no doubt that Katy is touring artist of our generation next to Beyonce so I don't think it's reaching since her impact is huge.

Topped with mega talent and beauty I can see why she's the biggest popstar in the world right now
Let's not forget sonically she's influenced candy-pop to return like Carly Ray Jepsen and Becky G. Katy ha power! And obviously the GP recognize her grand influence otherwise she wouldn't have been invited to perform at the Superbowl before her peers
