Who: Kate Bosworth
Style M.O.: Classic meets cool; mixing high-end designers like Burberry, Proenza Schouler, and Isabel Marant with vintage pieces and her own JewelMint jewels.
Why We Love Her: Kate excels at styling with an effortless, eclectic cool that's made her a modern-day icon — remember the American flag tee and denim cutoffs she wore to Coachella? She manages to look just as comfortable while running errands as she does on the red carpet, bringing a relaxed, cool-girl confidence to every ensemble.
