Today is Jane Birkin's birthday. At some point, the British-born actress, singer, and director (not to mention mum to new-generation It girls Lou Doillon and Charlotte Gainsbourg) became as frequently-cited a celeb style icon as Audrey Hepburn. Which is unexpected, given that Jane's signature style was so unpretentious. She wore her jeans to shreds, was frequently spotted sans shoes, and proudly carried a wicker basket as a purse — even after Hermès created its legendary Birkin bag just for her.
In honor of this inimitable star's birthday, we present seven very different celebs, all of whom have listed the eternal It Brit as their style icon. Take a look at how Birkin has influenced them all, and wish a very happy birthday to the queen of offhand cool.
