Mother Wore Tights is a 1947 American Technicolor musical film starring Betty Grable and Dan Dailey as married vaudeville performers, directed by Walter Lang.

In turn-of-the-century Oakland, California, the teenaged Myrtle McKinley (Betty Grable) is expected to follow high school by attending a San Francisco business college.

Instead, she takes a job performing with a traveling vaudeville troupe, where she meets and falls in love with singer-dancer Frank Burt (Dan Dailey).

Myrtle retires from show business after giving birth to daughters Iris (Mona Freeman) and Mikie (Connie Marshall), while her husband goes on tour with another partner.

Iris meets a well-to-do young man, Bob Clarkman (Robert Arthur), and is permitted to attend an exclusive boarding school there.
