Yves Saint Laurent is the French fashion house founded by Yves Henri Donat Mathieu-Saint-Laurent. The house and designer are often abbreviated as YSL. Cosmetics and perfumes have long been included in the designer’s offerings. The house’s first fragrance, Y for women, was launched in 1964. Y and several other launches by YSL, including Opium (1977), men’s scent Kourous (1981), and Paris (1983) have become modern classics of the perfume world and remain best-sellers.
