Who: Elizabeth Olsen
Style M.O.: Casual, polished chic with a sense of quirkiness; flirty blouses mixed with leather; lush, effortless pieces from Chloé, The Row, and Proenza Schouler; layered baubles with no-frills shoes and bags.
Why We Love Her: Elizabeth may have a famous and fashionable pair of siblings, but she's proving herself to be quite the sartorial star in her own right. She can go from cute and casual to full-blown retro glamour in a snap, and has been pretty much killing it at every red-carpet event thus far — showing us how to style up fresh, youthful looks with a very grown-up attitude.
