Yves Saint Laurent, or YSL, is one of the most famous fashion designers of all time, whose impact on the fashion world is almost unmatched. A revolutionary designer for women, his designs took traditionally male styles and reinvented them for the modern women of the 1960s. From jumpsuits to safari jackets to his iconic tuxedo, YSL's designs revolutionised women's clothes forever. He can be credited with making ready-to-wear clothes reputable and desirable, in a marked move away from haute couture, and for championing trousers for women.

Despite a life marred with addiction, war and mental health struggles, Yves remained a powerhouse of the fashion industry for 50 years, and his name and initials are now synonymous with quality, innovation and heritage. His collections may have sometimes generated controversy and criticism, but they have proved to be timeless and transformative.

The Little Guide to Yves Saint Laurent charts his tumultuous rise to the top, accompanied by facts and quotes from, and about, the man himself and the fashion legacy he built.
