The Caroline Sieber Look Book

Over the past five years, Austrian-born, London-based stylist Caroline Sieber has become a front-row fixture at all the top shows, leading Karl Lagerfeld to tap her as a Chanel brand ambassador. A true fashion girl's girl, she's the kind of woman who can try bold designer pieces — a bright red Valentino jumpsuit, for example, or a sheer Chanel minidress —  without straying too far from her signature style. Her trick for avoiding the "overdone" look lies in her taste for sleek, monochromatic outfits; even when she's wearing something particularly daring, she barely ever mixes prints or colors, and usually keeps fancy jewelry, makeup, and hair to a minimum. Click through to study her streamlined yet high-fashion aesthetic.
