Summary

ABOUT SAINT LAURENT

Founded in 1961, Yves Saint Laurent was the first couture house to introduce the concept of luxury prêt-à-porter in a 1966 collection called ‘Rive Gauche’, synonymous with youth and freedom. This shift represented a first critical step in the modernization of fashion and revolutionized the socio-cultural landscape.
In 1999, the luxury goods division of the Kering Group acquired Yves Saint Laurent and, under the creative direction of Anthony Vaccarello since April 2016, continues to position the house at the summit of the luxury universe.
Today, Saint Laurent collections include women’s and men’s ready-to-wear, shoes, handbags, small leather goods, jewelry, scarves, ties and eyewear.
