RIGHT AT GNOME: Mulberry returned to Los Angeles for its seasonal dinner at Chateau Marmont, where Bungalow One was decked out to resemble an English garden party, the theme of the spring/summer 2013 collection. This time, the brand mixed it up with slightly more accomplished actresses such as Elisabeth Moss, Kate Mara, Andrea Riseborough and Julie Delpy instead of its usual up-and-coming mix. It was a busy crowd: Mara just wrapped the Netflix series “House of Cards” with Kevin Spacey and Robin Wright, which she described as “a political drama where they both play really mean, awful people, which is great.” Riseborough, still promoting her IRA thriller “Shadow Dancer,” is also directing her first movie, the title and plot of which she was not yet ready to divulge. There were other directors at the long dinner table, including Delpy, who made fast friends with Moss, and Liz Goldwyn. After dinner, some guests took home the sorbet-colored garden gnomes that were used as props. “Does this look weird?” asked Shiva Rose, as she exited the bungalow with a two-foot-tall gnome under each arm. “Hey, you’re rollin’ with the gnomies,” offered a doorman.
