When it comes to nails, Katy Perry is an early adopter. She and Rihanna were some of the first celebrities to wear Minx, and she's definitely been ahead on nail art and texture trends. So it was interesting to see that last night hosting the Teen Choice Awards she went with holographic sparkle nails. They were much more demure than we'd expect from her, and a big departure from the chunky, matte nails that have dominated lately. If Katy's nails are a good predictor of things to come, are you excited for the return of sparkle polish?
