Saint Laurent-Yves Saint Laurent is a luxury fashion house founded by designer Yves Saint Laurent and his partner Berger. The style is refined and elegant, and the previous main designer was Hedi Slimane, who has now left. The original women's clothing style borrowed a lot of items from men's clothing, such as suit pants, sports jackets, etc., which increased brand awareness. YSL also deals in cosmetics such as perfumes.
