My two favorite French countesses, Jacqueline de Ribes, named "the most stylish woman in the world" and Marie-Laure de Noailles, surrealist patron and visionary of Villa Noailles.
Jacqueline de Ribes is a lady of leisure who longed to design clothes. She began showing her collections in 1983 and continued until 1994. She lives in Paris and in Spring 2010 she received the French Légion d'honneur. See the Vanity Fair profile on de Ribes here and more photos here.

Marie-Laure de Noailles was a patron of the arts supporting Dali, Breton, Buñuel and others. When she was given land to build a vacation home she hired a film set designer, Robert-Mallet Stevens. The innovative villa included a kitchen open to the outside and an automated clock system and now hosts annual fashion and photo festival. See photos here.
