Celebrity Style: Miranda Kerr, Rachel Bilson, Kate Bosworth

Who: Nicole Richie

Style M.O.: Rocker-cool with a bohemian twist; cat-eye sunnies and faux fur touches; carry-everything satchels; sky-high pumps and ankle boots.

Why We Love Her: Nicole's style has evolved from the hot yellows and pinks that once dominated her wardrobe to a sleeker, more vintage-inspired style. Nicole sticks with her boho vibe, but often switches it up with sexy, streamlined LBDs and a dark, moody color palette. As a designer and working mom, we can count on Nicole for cool get-up-and-go ensembles — but she always keeps us on our toes.
