My Wife's Suitor(1959)

The jobless Somaa is happily married to Lola. He finds a job as a secretary at a fashion house owned by the spinster Howayda, who lives with her brother Fawzy. But as the job requires that the secretary be single, Somaa claims he is. When Lola finds out, she asks Somaa to quit, but he refuses, so she starts working as a model for Howayda, whereupon Fawzy falls for Lola and proposes to her.
