WHO WORE IT BETTER? KATY or KIM?

 Katy Perry stepped out for designer Karl Lagerfeld's dinner party in Paris, France in March wearing this super-sexy Balmain dress. Weeks later, Kim Kardashian rocked a very similar frock from the designer's collection to the premiere of her boyfriend Kanye West's "Cruel Summer" short film at the Cannes Film Festival, also in France. While Perry pulled the look together with open-toed sandals and an electric-blue 'do, Kim let her famous curves do the talking, slicking her hair back and donning black ankle booties.

So who do you think wore Balmain's designs best -- Katy or Kim?
