Legendary French designer Hubert de Givenchy who helped Audrey Hepburn and Jacqueline Kennedy become fashion icons, has died, according to statements issued by his international firm and family on Monday.

The founder of the legendary House of Givenchy set the style guidelines for aristocratic chic to follow during the 1950s and 1960s, created the iconic Little Black Dress, affectionately referred to sometimes simply as the LBD, and had an illustrious list of clients.

"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," a statement said.

Givenchy's longtime partner and former haute couture designer Philippe Venet, also announced his death, saying that it was "with huge sadness that we inform you that Hubert Taffin de Givenchy has died," in his sleep.

The designer's "nephews and nieces share Mr Venet's grief," the statement said.

His elegant, restrained style continue setting the dress style standards to the wealthy elites from Queen Elizabeth II of England to older American and Chinese socialites.

The funeral will be a strictly family affair, a statement added.
