Daughter of the politician Fernand Chapsal and of the Madeleine Vionnet dressmaker, Marcelle Chaumont.
Both her bias cut and her urbanely sensual approach to couture remain a strong and pervasive influence on contemporary fashion as evidenced by the collections of such past and present-day designers as Ossie Clark, Halston, John Galliano, Comme des Garçons, Azzedine Alaia, Issey Miyake and Marchesa.
In 1933, Mona was named "The Best Dressed Woman in the World" by Chanel, Molyneux, Vionnet, Lelong, and Lanvin, becoming the first American to be so honored.
From 1919 to 1925, Thayaht worked as a designer in collaboration with Madeleine Vionnet, the couturière credited with introducing the bias-cut to Parisian fashion.
