Year founded: 1961

Hedi Slimane's tenure at Saint Laurent has done more than just alter the name of the brand. Formerly under the guidance of Italian Stefano Pilati, the brand's almost sudden shift from a sprezzatura-esque tailoring to '60s-'70s rock design focus was a visual herald of the Slimane's coming. Currently the brand epitomizes Slimane's skinny, rock-n-roll aesthetic, with it's recently established “Permanent Collection” including brand signatures like L17 motorcycle jacket, a polka-dot silk button-up, Le Smoking blazer, and low-waisted skinny jeans. Considering the Yves Saint Laurent himself revolutionized skinny fit clothing with a modern sense of shape that we use even to this day, perhaps Slimane's radical direction isn't too far off-base.
