Long before Gone Girl’s “cool girl” rant made cool a negative term, there was, and is, the original cool girl, Joan Didion. In a perfect marriage of cutting-edge fashion and American literary royalty, she is now the new face for the Spring 2015 line of fashion label Céline, designed by British designer Phoebe Philo.

Photographed by Juergen Teller, Didion is a great choice, not least because the internet has made much of Didion’s fashion sense in recent years. From sharing the effortlessly stylish images of her pausing mid-smoke or looking gracefully distracted as she leans out her car window, to copying and pasting Didion’s packing list from titular The White Album essay, literary nerds are not Didion’s only admirers. An indelible part of US literary culture, she’s the perfect fit for Céline, Philo no doubt hoping that fans will see Didion’s famously spare prose as analogous to the label’s brainy, minimal cool.

Céline is not the only fashion label to feature older women in its ads. Dolce and Gabbana made headlines in December for featuring elderly Italian women for its Spring 2015 line, while Lanvin cast 82-year-old Jacqueline Murdock in its Spring/Summer 2012 campaign. That year, Angela Lansbury made the cover of The Gentlewoman’s 2012 issue. Now 89, she is almost a decade older than Didion.

The ad campaign comes as the notoriously reclusive writer has been the subject of a wave of press in the past few months. Didion’s nephew, Griffin Dunne, launched a successful Kickstarter campaign for a documentary of Didion’s life. In November, her memoir Blue Nights was read onstage by Vanessa Redgrave.
