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.
Laurent's career in fashion began at the tender age of 17, when he served as assistant to Christian Dior.
Laurent became known for his exquisitely-tailored women's suits, and is credited with creating the first women's tuxedo. 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 Rive Gauche (1970), Opium (1977), men's scent Kourous (1981), and Paris (1983) have become modern classics of the perfume world and remain best-sellers. The company continues to earn new fans with contemporary releases such as Baby Doll (2000), Elle (2007) and La Nuit de l'Homme (2009). YSL offers fragrances in conjunction with L'Oreal Group.
