You Were Never Lovelier is a 1942 American musical romantic comedy film directed by William A. Seiter and starring Fred Astaire and Rita Hayworth.

The film, a Hollywood remake of the 1941 Argentine romantic comedy Los martes, orquídeas (On Tuesdays, Orchids),[3] is set in Buenos Aires.

After he loses his money gambling in Buenos Aires, he goes looking for a job with Eduardo Acuña, the wealthy owner of a nightclub.

Bob's friend, bandleader Xavier Cugat, invites him to perform at the wedding of Acuña's eldest daughter, Julia.

During Julia's wedding reception, Bob is attracted to Maria, but his advances are rebuffed by her, and she refuses to speak to him.

Aware of his younger daughters' plight, Acuña works out a plan: he sends orchids and anonymous love notes from a supposed secret admirer to Maria to help get her in the mood.

Although Hayworth had a fine voice, Harry Cohn insisted on her singing being dubbed throughout by Nan Wynn.

The film is a reworking of the 1941 Argentine musical Los martes, orquídeas (On Tuesdays, Orchids) directed by Francisco Múgica.
