Beginning with the Elle Women in Hollywood Awards and closing out with the Fashion Group International’s 30th Annual Night of Stars gala, this week’s social calendar was particularly jammed — featuring notable appearances by everyone from Renée Zellweger to Debbie Harry. Earlier in the week, January Jones, Paris Hilton, and Jaime King all turned out to celebrate the openings of West Hollywood’s new Restoration Hardware megastore, while back in New York, Olivia Munn attended the American Ballet Theatre’s Scarlett, White, and Blue fall gala wearing a tutu that could very well double as a Black Swan Halloween costume. Meanwhile, Natalie Joos clowned around with a succulent on her head at the J Brand on Spring launch party, and last night, Emily Weiss threw a party for her new beauty line, Glossier, with Emily Ratajkowski.
