Katy Does Throwback Denim–Pop star Katy Perry gave a totally throwback moment at the 2014 VMAs wearing a denim look inspired by Britney Spear’s matching style with Justin Timberlake at the 2001 show. Katy’s date for the night was rapper Riff Raff, and the pair wore custom Versace denim outfits bedecked with jewels as accessories. Last year Katy wore leopard print designed by Emanuel Ungaro.
