Philippe Clarence, a famous Parisian dressmaker, seduces his friend's fiancee. But, for the 1st time in his life, this is for real. The film is also a sharp picture of the fashion world. A philandering young dress designer plays fast and loose with the hearts of all the fair maidens he encounters, and leaves them in a Paris lurch. But when he meets the fiancée of his best friend, he falls deeply and truly in love with her. The girl is soon faced with two choices; marry the reliable fiancée whom she doesn't love, or run off with the dress designer with whom she is infatuated. She sees that she also has a third option and makes the wise choice...she rejects both. The dress designer is not too well equipped for accepting rejection, and he makes a bad decision.
