One perk of being a celeb? Getting your hands on dresses before they even hit the stores.

Both Nicky Hilton and Katy Perry preened in this peacock dress from Matthew Williamson's collection for H&M (which doesn't come out until April 23) at red carpet events last week.

Katy paired it with black tights and a funky purse, while Nicky kept it simple with bare legs and coordinating blue pumps.
