Rachel Bilson shot to fame on The O.C. and has stayed on our radar because of her relaxed yet stylish off-duty dress-sense. Rachel is a huge fan of Chanel, and thus a friend of Karl Lagerfeld - she is regularly seen with a covetable Chanel bag on her shoulder. Rachel's off-duty style mixes carefree layers (vests, oversized cardigans and blazers) with casual denim, boyfriend style trousers and floral mini-dresses, while her feet are almost always another attention-grabbing part of her outfit, whether she's wearing studded gladiator sandals or towering lace-up ankle boots. Rachel's style is typically Californian: feminine, a little boho and a mixture of designer pieces with lesser known labels and once-off finds. Take a look at some of her best street style moments below.
