Misbehaving Ladies 1931

Ellen, a young American girl who married a European prince and moved to his country, is preparing to return to the US, after having paid off all the debts left by her now-deceased husband. However, when she returns early, no one recognizes her and even her aunt Kate mistakes her for the princess' dressmaker. Her ex-boyfriend Joe, who recognizes her immediately, suggests that Ellen continue with the charade and have some fun, but a series of misunderstandings causes trouble for her.
