Madame Marty is one of Madame Desforges’s friends and is the first of the aristocratic ladies to start shopping at the Ladies’ Paradise. Throughout the novel, she and her daughter Valentine show themselves to be utterly incapable of resisting the appeals of the Ladies’ Paradise. She goes into fevers of excessive spending, making fewer and fewer excuses as the story goes on. Her spending makes Monsieur Marty go broke and drives him into a fit of mania. Despite this, Madame Marty goes to live with an uncle and continues to shop, presumably spending the uncle’s money.
