In 1981, The House of Givenchy was split into a perfume line, which went to French champagne house Veuve Clicquot, and a fashion branch that was acquired by is European multinational luxury goods conglomerate LVMH in 1989.
Thus began a decades-long friendship that saw Givenchy dress the star in almost a dozen films, including the 1961 hit "Breakfast at Tiffany's".
But the designer is best known for the "little black dress" worn by Audrey Hepburn in Breakfast at Tiffany's.
"His are the only clothes in which I am myself", Hepburn said of the designer. "He is more than a designer, he is a creator of personality", Hepburn once said of her friend.
His label paid tribute to its iconic founder on social media as news of his passing broke, revealing "he will be greatly missed".More news: Nepal's first woman president wins second term
The Givenchy name and influence endures.
"According to BBC:" Givenchy came from an aristocratic background, and worked alongside the then unknown Pierre Balmain and Christian Dior after World War Two.He was employed by the avant-garde designer Elsa Schiaparelli before leaving to found his own fashion house in 1952.
Born into aristocracy, his famous clients also included Elizabeth Taylor, Jackie Kennedy and Princess Grace of Monaco. He reportedly died on Saturday in his home outside the French capital of Paris at 91-years old. He remained head of creative design for seven years before retiring in 1995, reports Elle UK.
John Galliano, Alexander McQueen and Riccardo Tisci have all since served as creative directors of the label, with former Chloé designer Clare Waight Keller now helming the house.
"The definition of a true gentleman, that will stay with me forever". You've probably already spared five minutes over your morning coffee to muse over the French couturier's legacy of elegance and the women he dressed, so consider this more of an ode to the way Givenchy democratised fashion rather than a mere biography.
