Mrs. ‘Arris Goes to Paris (1992)

Ada Harris, a London charwoman in the 1950's, sees a Dior dress and decides that she's going to own one. First, she scrimps and saves her money, but when she has enough, and takes a trip to Paris, she learns that buying an original couture creation is a little harder than simply plunking down cash. Along the way to her goal, she manages to befriend a count, unite young lovers, and dodge customs.
