What is "ex-lady"

Ex-Lady is a 1933 American Pre-Code comedy film directed by Robert Florey. The screenplay by David Boehm is based on an unproduced play by Edith Fitzgerald and Robert Riskin. It is a lightweight and modern version of a drawing room comedy. The film was made before the Motion Picture Production Code was in force, and it is risqué: in subject matter (people having affairs without shame), in staging (double beds) and in the fairly revealing negligees that Bette Davis's character wears.
