Spy Girl

Loulou de la Falaise is best known for being the muse of Yves Saint Laurent for over 30 years. She is the daughter of Count Alain de la Falaise. Her mother, Maxine, was a 1950's fashion model.

Loulou met Yves in the summer of 1968, when she was 21. He fell immediately in love with her. She had a different style than the French women he knew. She mixed her old world lineage with a carefree bohemian look of swinging London that was prevalent in the late sixties, but had not reached Paris yet.

Their relationship blossomed and extended beyond friendship and into the YSL's pret-a-porter designs. Loulou collaborated with Yves until his death in June of 2008.

Loulou's first husband was Desmond FitzGerald, the Knight of Glin. After their divorce, she married the artist Thadee Klossowski, son of the painter Balthus. They had one daughter, Ann. Today de la Falaise runs a boutique in Paris called Maison de Loulou.

Spy Girl

Betty Catroux is a former Chanel model and fashion icon. She has also been labeled a muse by Yves Saint Laurent. Born Betty Saint, she is the only daughter of Carmen Saint, a Brazilian socialite and Elim O'Shaughnessy, an American diplomat.

Betty met Yves when she was 23 at Regine's, the notoriously gay Paris nightclub, in the mid sixties. She had long straight platinum-blond hair set against an angular face. Her androgynous appearance, lanky body and super long legs impressed Yves. With their similar body types, he often referred to Betty as his twin sister. Perceiving her as a femme fatale, she took on a visual inspiration for Yves, which translated into his designs.

In 1968, Betty married French interior decorator, Francois Catroux. The couple has two daughters, Maxine and Daphne.

In 2002, Tom Ford dedicated his debut YSL Rive Gauche collection to Catroux.
