Is This the Coolest Céline Ad of All Time?

Phoebe Philo might just be a genius. The creative director of Céline has not only managed to skyrocket the brand into major It-girl status during her reign, but she also had the inspiring idea to feature legendary cool girl and prize-winning author Joan Didion in Céline's S/S 15 ad campaign.

The 80-year-old Didion has always embodied an effortless style that's a perfect match for the Parisian brand. In the campain, she's wearing Céline's in-demand oversized shades, a classic black sweater, a statement pendant, and her trademark whispery silver bob. Being an octogenarian never looked so fabulous.
