Plot
The film tells the story of fashion designer Yves Saint Laurent at the peak of his career between 1967 and 1976. The film starts with Saint Laurent alone and depressed in a hotel room apparently after a night of partying in Paris nightclubs. He is placing a call to a newspaper journalist to grant a tell-all interview which he had previously declined.
In the mid-1960s, Saint Laurent emerges as a leading voice in French fashion. His business begins to flourish and grow internationally. Less well known about his private life is his love of the Paris nightlife, and the clubs and homes of the rich and avant-garde. Saint Laurent enjoys the nightlife and the endless hours of champagne, pot, and drugs which seem to surround him at every turn. During one evening, he sees an attractive model, Betty Catroux, at a nightclub and approaches her about becoming a model for his fashion house. She turns him down saying that she is under contract with Chanel. Saint Laurent is persistent and keeps repeating his requests, while continuing to flatter her good looks. As the evening progresses, the two begin dancing together on the discotheque floor, and then start to mingle having drinks together. Later that week, Betty is seen in Saint Laurent's studio modeling his new designs for him while he creates his new fashions, and Saint Laurent celebrates having recruited one of Chanel's top model for his own fashion house.
Saint Laurent's success continues and he forms a long-term same-sex relationship with his business manager, Pierre Bergé, which is profitable to both men financially and in their personal emotional lives. Saint Laurent's use of alcohol and drugs seems to continue and to grow along with his international success as a fashion designer. On one night out of partying, a young male operative named Jacques de Bascher spies out Saint Laurent and approaches him with plainly presented romantic and sexual intentions. Saint Laurent is captivated by his good looks and the two begin an intensely explicit affair. Their preferred mutual habits of enjoying the Paris nightlife and drug use seem to spiral them out of control into a tumultuous relationship. Saint Laurent's long-term affair with Pierre at this fashion house in put on hold as Saint Laurent continues his new romantic affair with Jacques.
When Saint Laurent wakes up one morning in his hotel room, seemingly alone and dejected, he calls the newspaper journalist whom he had previously declined to interview with, and now present his own sensational tell-all version of his sexual proclivities and his penchant for the Paris nightlife. When his office and Pierre later learn that the newspaper is planning to proceed with the tell-all interview, they react harshly and threaten legal action for defamation and libel against the newspaper if they go ahead with publication. They state that the telephone interview was a prank by someone unknown to Saint Laurent and that printing the interview would only cause the newspaper embarrassment to their own reputation as journalists, as well as years in court defending themselves against a costly lawsuit for libel.
The film moves forward in time, showing Saint Laurent in old age living in his opulent Paris apartments surrounded by fine art and expensive fetishist possessions in his collection of exotic leopard skins and other wildlife shown on display throughout his flat. Saint Laurent dies in old age having become one of the most accomplished Paris fashion designers of the 20th century.
