Known for his sleek and understated aesthetic, Hedi Slimane has been a pivotal force at some of fashion's biggest houses-Yves Saint Laurent, Dior Homme, and now, Celine. Notoriously secretive, the French creative lets his minimal, edgy garments do the talking.

Starting his career off at Dior Homme in the early 2000s, Slimane established himself as a major force within the menswear industry. Slimane's approach to menswear was wholly unique for the time. With skinny suits, kilts, and angular silhouettes, the designer bravely took an androgynous approach to menswear at the famed French house.

Continuing this polished approach, Slimane had a stellar tenure as the creative director of Yves Saint Laurent from 2012 to 2016 that saw him experiment with new fabrications and expand his sartorial lexicon. Today, the designer is head of luxury house Celine, where he has established a distinct wardrobe blending French bourgeois with modern themes. To celebrate Slimane's 53rd birthday, L'OFFICIEL rounds up his 11 most memorable runway moments from his high-profile creative director stints.

Titled Victim of the Crime, Slimane's Dior Homme Fall/Winter 2004 collection embodies the designer's sleek and edgy vision that he brought to the French house. With pleated kilts, slinky ready-to-wear, and versatile outerwear, the runway show displays Slimane's immense menswear know-how and distinct eye for innovation.

Dior Homme Spring/Summer 2006

Yves Saint Laurent Spring/Summer 2013

Slimane's womenswear debut at Yves Saint Laurent is a showstopping melange of reimagined corsetry, foreboding dresses, and sultry hats that concealed several of the models' faces.
