The beginning of the film is supposed to be set around 1914 and continues through the next 17 years until 1931, but the females of the cast wear strictly 1931 fashions all the way through. Likewise, the popular music played at the night club, as well as the interior design, is also strictly 1931, regardless of the year it's taking place.
