Three decades in Hollywood
Los Angeles is where Birgit learned to design for the camera. From studio feature films to ten years at the heart of a global television drama, and from luxury brand partnerships to leading a transatlantic business council, the city shaped the way she works.
Studios and screen
Birgit's Hollywood career began on productions at Paramount, Sony, Disney and Universal. In 2001 she became head costume designer of CBS's The Bold and the Beautiful, a drama set inside a fictional Los Angeles fashion house and watched around the world. For ten years she dressed its cast in runway couture and fine jewelry, winning three Daytime Emmy Awards. In 2016 she brought that experience to Global Beauty Masters as fashion director and mentor.
