Zac Posen
As one of the most famous fashion designers in the country, it should come as no surprise that Zac Posen has some of the most authentic and detailed Halloween costumes out there. Each year he shows them off at, of course, Heidi Klum’s Halloween party, and he always looks incredible.

Obviously, the celebrities that are invited to Klum’s exclusive party each year know that they are expected to look their best. Zac Posen showed that it wasn’t a problem for him when he arrived dressed as Willy Wonka and nearly unrecognizable. The fashion designer stole the show, and we can only hope that he did some somersaults down the hallway.
