She began her career in the 1960s as a model for Parisian Haute Couture Houses of Nina Ricci, Jean Patou, and André Courrèges.
At the time models had to provide their own shoes to match the clothes designers assigned them for their runway shows and photo shoots.
Building on the traditions of Beth Levine and foreshadowing the later designs of Manolo Blahnik, Frizon shoes were showy and extravagant, and her name joined the ranks of the haute couture boutiques.
Frizon often used expensive and everyday materials together in unusual combinations: lizard and snake, suede and satin, canvas and crocodile.
[2] She is credited with introducing the 1978-79 cone heel that continued into the early 1980s,[3] and she was the exclusive shoe designer at that time for the influential Thierry Mugler and Claude Montana lines.
