The Swarovski-hosted bash to toast Karlie Kloss on her new brand ambassadorship on Tuesday night had all the makings of a successful fashion party: a Harley Viera-Newton playlist; bursts of pink peonies everywhere; truffle-tinged hors d’oeuvres, etc. There was only one component missing — a conspicuously absent Kloss. The megamodel was over an hour late to her own party — no matter. When she arrived, she breezed into the Top of the Rock all smiles and sparkle. And she seemed to be fully embracing her new role. “I so am honored to be part of the Swarovski family and to celebrate with them tonight. The Swarovski collection allows me and women everywhere to shine, no matter what the occasion, in everyday and extraordinary moments,” she said, dripping in the brand’s crystals. Fellow attendee Hailee Steinfeld was also bedecked in jewels, though she had a slight disadvantage should there be a bling-off. “Well, I don’t have my ears pierced. I’m too indecisive,” she shrugged.
