Katy Perry "Nails" It in NYC

Katy Perry is all about her quirky Cali girl fashion, whether that be a whipped cream launching bra, gold hot pants, or even a carousel dress.

Katy covered up the skin-tight purple cupcake dress she wore during her performance with a sparkly black shawl, which went perfect with her glittery fingerless gloves.
