The Paris-based art director and mega stylist co-founded Petronio Associates in 1993 with ex-husband Ezra Petronio. The creative agency counts Prada, Chloe, Miu Miu, Saint Laurent, and Chanel among its clients. The duo also founded Self Service Magazine, a fashion and cultural biannual held in high regard by industry insiders. And she’s the fashion director of the cutting-edge Parisian newspaper supplement M Le Magazine du Monde.
You can spot her signature look a mile away – Phoebe Philo-era Celine plus Chanel staples, all in beige and topped with red nails. Tres French chic.
Why know her
As one of the world’s top tastemakers, Koller’s street cred is unrivalled. Many images she has styled are modern classics: Recall her blackand- white spread with lensman Karim Sadli. And she champions new talent, including women photographers Harley Weir and Bibi Cornejo Borthwick. She also styles and does consults for ad campaigns by top brands, from Givenchy to Lacoste. Her magic touch is not only for the luxury market: She recently worked with fast-fashion juggernaut Zara, and released a capsule collection for Fall 2019 with French retailer A.P.C. that personifies her Parisian cool.
