"She did mine, so I hope she does [Kim's]," Khloe told E! News. Wang also designed the wedding dresses of stars like Mariah Carey, Victoria Beckham and Sarah Michelle Gellar. "Just because I love her, and I feel like when you think of weddings, you think of Vera Wang. I think it would be a perfect fit."
