Sonia Rykiel has taken it back to where it all began for its SS15 campaign and hit Saint-Germain-des-Prés in Paris with Elizabeth and Georgia May Jagger. Juergen Teller, shot the new ads in quintessentially Parisian parts of the 6th arrondissement: the parks, cafes and cobblestoned streets of the Left Bank.

In fact, not too unlike the streets that the Jagger sisters' mother, Jerry Hall, probably walked down back when she modelled for Rykiel a few decades ago. The brand explains that keeping it in the family was part of the appeal. 

"Their mother walked for Sonia Rykiel and they would come to the boutique. It's the story of a family and of a family business. It was great to have Juergen shoot them in such spontaneous fashion," artistic director Julie de Libran said. "I loved the energy that passed between them and their individual beauty so equal yet unalike."

"We all had a lot of fun on the shoot and the girls just typify the kind of woman that Julie designs for," stylist Alexia Niedzelski said. "Sexy, modern and strong-willed."
