Last night's Chloé fashion show in Los Angeles drew a star-studded crowd, which showed that you don't need to dress solely in muted colors come Fall. Balking tradition, Nicole Richie was the ultimate fashion rebel in an entirely white-after-Labor-Day look (we especially love that loosely cut tuxedo-inspired blazer!) whose only accents of color came from a gray belt and steel-blue clutch. January Jones went bold in a blue dress with lace overlay, accessorized with black clogs. Alessandra Ambrosio went for a champagne-colored top, which she tucked into a perfectly tailored pair of black pants, and Rachel Bilson wasn't afraid to cover up in a white buttoned-up blouse and striped maxi skirt. Not a stitch of cashmere or tweed in the bunch — whose not-so-Fall style do you like best?
