Wow so next time she should come covered from head to toe maybe that will be nun enough for them 
I liked Katy's outfit in this concert. I find it adorable and kind of Wonder Woman like. Which is the look and theme Katy was going for. She was not at all inappropriate.
She could have worn the yellow dress she wore at Monday's inaugural ball ,which covered a lot more and is also adorable, and the critics still would have complained.
