I know it was Diddy's celebration, but the Kardashians kind of stole the night! Especially Kim Kardashian. She wore a vintage Vivienne Westwood wedding dress to Diddy's 50th birthday party and all eyes were on her and Kanye. This entire look was complete perfection, including her Old Hollywood Glam inspired hair and makeup. And, Kanye looked pretty good too in his navy Burberry suit!
