Founder: Hedi Slimane
Year Founded: 2001 - 2007

The slim and fragile looking Hedi Slimane started designing for Yves Saint Laurent in 1997, creating slim, closely cut silhouettes that built on the minimalism of Helmut Lang and Jil Sander. In 2001, he switched to Christian Dior, where he created a conspicuously chic collection of superslim suits under the Dior Homme label. His very modern view of tailoring sparked a new interest in fashion suits among younger consumers, which arguably led to a greater interest in men's tailored clothing in general.
