It felt like Zac Posen was Mr. Popular at tonight's Costume Institute Gala at the Metropolitan Museum of Art . He showed up with Dita Von Teese  on his arm, but she wasn't the only beauty wearing one of his creations. Karen Elson and Liu Wen also showed up in ball gowns imbued with his signature glamour, and we're honestly so wowed that we aren't sure if we can pick a favorite!
