Fashion giant Hubert de Givenchy died on Saturday, March 10, 2018, at the age of 91. The French aristocrat founded the House of Givenchy in 1952 and is perhaps best known by the general public for creating the professional and personal wardrobe of long-time style icon and actress Audrey Hepburn. Her famous outfits in “Breakfast at Tiffany’s,” “Sabrina,” “Funny Face” and “How to Steal a Million” were all Givenchy’s creations. Hepburn’s classic little black dress in the opening scene of “Breakfast at Tiffany’s” remains one of Givenchy’s most well-known designs. In addition to Hepburn, Givenchy also designed clothing for First Lady Jackie Kennedy, Princess Grace of Monaco and Wallis Simpson.

Givenchy and his company redefined elegance and refinement since the brand’s founding in 1952. Givenchy retired from the House of Givenchy in 1995 after selling the label Givenchy Couture Group to LVMH in 1988 for $45 million. Givenchy remained the head of creative design until he retired and decided to became an antiques expert for Christie’s, the Chateau de Versailles and the Louvre Museum. Though Givenchy took a step back from the fashion world after his retirement, the House of Givenchy will miss its founder. A tweet on Monday morning from the fashion house read, “The House of Givenchy is sad to report the passing of its founder Hubert de Givenchy, a major personality of the world of French Haute Couture and a gentleman who symbolized Parisian chic and elegance for more than half a century. He will be greatly missed.”

The House of Givenchy also reminded the world of Givenchy’s ties to Hepburn in another statement. “He revolutionized international fashion with the timelessly stylish looks he created for Audrey Hepburn, his great friend and muse for over 40 years. His work remains as relevant today as it was then.”

Bernard Arnault, the chairman and chief executive officer of LVMH, spoke about Givenchy’s death and legacy as well. “[Givenchy] was among those designers who placed Paris firmly at the heart of world fashion post 1950 while creating a unique personality for his own fashion label,” Arnault said. “In both prestigious long dresses and daywear, Hubert de Givenchy has brought together two rare qualities: to be innovative and timeless.”

Givenchy’s designs have become such classics that Givenchy was given his own exhibit at the Museum of Lace and Fashion in Calais. “It was always my dream to be a dress designer, and my mother accepted that decision,” Givenchy said. “I am happy because I did the job I dreamt of as a child.”

Givenchy is survived by his partner, his nieces and nephew and their children.
