About this role
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.
Today, Saint Laurent collections include women’s and men’s ready-to-wear, shoes, handbags, small leather goods, jewelry, scarves, ties and eyewear.
