Vamp Till Ready (1936)

Charley (Charley Chase) is married to a very plain, old-fashioned girl, Wilma(Wilma Cox),and when he ridicules a dress she is wearing, she resolves to "doll up." Charley returns home and finds her garbed in a beautiful evening gown, but mistakes her for her twin sister, whom Charley knows is opposite of his wife and modern in every respect. When she realizes that Charley thinks she is her sister, she tells Charles that Wilma is in bed with a headache and suggest, just to see how far he will go with another woman, that they go to a party. Although feeling guilty about leaving his wife at home, Charlie agrees. There, Wilma tries to seduce him to make love to her but Charlie is faithful to his wife and departs and leaves what he thinks is the sister at the party. Wilma now has to beat him home before he can discover she is not home in bed with a headache. Complications arise.
