Sienna's style has always been a little bohemian and undone. Whether she's working the red carpet or hanging out backstage at a festival, she has an eclectic, unconventional and upbeat style that girls the world over try to emulate.
Sienna's beauty rules are simple, she favours nourishing, natural products like Korres and Elemis and when it comes to make-up, she creates her night time look with Bobbi Brown's Gel Eyeliner, perfect for creating graphic 1960s eyes that last all night long. She keeps her complexion clear with Susan Posnick's ColorFlo, a super light mineral make-up base. Click the products to read more about Sienna's favourite beauty buys.
