Even if you were keeping tabs on Katy Perry at the Grammy Awards, you could've missed the singer's many costume changes. We won't blame you — between the arrival, the performance, and the afterparty, there was a lot to keep track of. In fact, if you didn't spot Miss Perry sitting in the audience, you already missed one of her four ensembles.
Not to worry, we've got it all well-documented right here. Check out every outfit from the costume chameleon.
