Which American socialite was a close friend and client of Cristóbal Balenciaga?

Mona von Bismarck was the American socialite who was a close friend and client of Cristóbal Balenciaga. Born Mona Strader in Louisville, Kentucky, she became one of the most visible and influential American patrons of mid-century haute couture.

Bismarck was more than an occasional customer. Balenciaga dressed her for many settings, creating everything from elaborate evening gowns and ballgowns to practical clothing for her villa in Capri, including gardening garments. Her loyalty helped make her one of the defining figures in the designer’s elite international clientele.

Her fashion reputation was formidable: in 1933, she became the first American named the world’s best-dressed woman in a poll conducted by French couturiers. She was also a philanthropist and patron of the arts, and artists such as Salvador Dalí and Cecil Beaton helped shape her public image.

The strongest clue to the friendship is the reaction attributed to her when Balenciaga closed his atelier in 1968. Diana Vreeland said Bismarck stayed in her Capri bedroom for three days, illustrating how deeply she identified with the house. Gloria Guinness was also a famous Balenciaga client, but Mona von Bismarck is the canonical answer here.
