Nicole Richie and Erin Wasson are two of America\'s most stylish stars. Nicole is the petite It-girl with a bumper profile and a bank balance to match. She is the poster girl for the rich hippy look: all boho floaty dresses, fringed scarves and embellished headbands. She recently turned jewellery designer creating her own line, House of Harlow 1960. Meanwhile, Erin, supermodel, stylist and one-time muse to designer Alexander Wang, has long been admired for her non-conformist approach to fashion. The 27-year-old Texan has perfected LA\'s laid-back cool in an off-duty uniform of cut-off denim shorts, slouchy tanks and mannish boots. Whether it\'s a tailored blazer or an evening dress she always manages to put her unique stamp on it and recently collaborated with skating brand RVCA to create a capsule collection of clothes in her signature low-key style. Who will win the fashion face-off? Let\'s take a closer look...
