Billboard Music Awards 2012: All The Gowns

The 2012 Billboard Music Awards on Sunday night (20 May) brought a whole heap of glitz and glam to Las Vegas (because what Vegas is really lacking right now is glitz and glam). From Zooey Deschanel in glittery Moschino and opaque tights to Carrie Underwood's Disney Princess-adjacent Oscar de la Renta and from Miley's blazer to Katy Perry's slinky sequins, here are all the evening's gowns*.
