Katy Perry took the Grammys red carpet by storm tonight in a dazzling seafoam green John Mayer, in the audience. Katy's look is not only supersexy, but it's also a mature, sophisticated departure from the star's signature flirty hemlines and candy-colored hairstyles - she played down the revealing cutout and embellished neckline of her dress with sleek, jet-black hair and dark eyeliner. Are you a fan of Katy's look tonight?
