Quality Street is a 1937 American historical comedy film made by RKO Radio Pictures.

The screenplay was by Allan Scott, Mortimer Offner, and Jack Townley, based on the 1901 play Quality Street by J. M. Barrie.

Twenty-year-old Phoebe Throssel (Hepburn) becomes very hopeful when one of the few, Dr. Valentine Brown (Tone), tells her he has something important to say to her that day.

By contrast, the Throssels' servant Patty, though she is a decade older and aware she is no beauty, is confident that she will get a man.

To lift her spirits, Phoebe sheds her drab everyday clothes and dresses up in a beautiful gown.

When Brown returns unexpectedly, Patty thinks quickly and identifies her as Phoebe's niece Livy.

The next day, the Throssels have to fend off their neighbors, the Willougbys, who suspect that Livy and Phoebe are one and the same, particularly elderly Mary Willoughby.
