The eponymous brand was founded by designer Yves Saint Laurent and his partner, Pierre Berge in 1961, and the current logos were designed in 1963 by A.M. Cassandre. During the 1960s and 1970s, the firm popularized fashion trends such as the beatnik look, safari jackets for men and women, tight pants and tall, thigh-high boots, including the creation of arguably the most famous classic tuxedo suit for women in 1966, Le Smoking suit. He was the first, in 1966, to popularize ready-to-wear in an attempt to democratize fashion, with Rive Gauche and a boutique of the same name. The brand continued to expand in the 1980s and early 1990s with fragrances for both men and women, having launched its cosmetic line in 1978. In 1993, the Saint Laurent fashion house was sold to the pharmaceuticals company Sanofi. In 1999, Gucci (owned by PPR) bought the YSL brand and asked Tom Ford to design the ready-to-wear collection while Saint Laurent would design the haute couture collection. Saint Laurent closed the couture house of YSL in 2002. The pret-a-porter line was produced under the direction of Stefano Pilati after Tom Ford left in 2004. In 2012, Kering (previously known as PPR) announced that Hedi Slimane replaced Stefano Pilati as the creative director. Slimane chose to rebrand as Saint-Laurent which sparked a lot of controverse. In 2016, Hedi Slimane left Saint Laurent replaced Anthony Vaccarello.
