Madcap Madge (movie, 1917)

The social climbing Flower family is comprised of Mr. Flower, a banker who has overextended himself financially, Mrs. Flower, a socially ambitious mother, Julia Flower, a marriage-minded elder daughter and Madge Flower, a high-spirited younger daughter. When Madge is expelled from boarding school for her practical jokes and pranks, she joins her mother and sister in Palm Beach, where they are wintering, in hopes of snaring a titled husband for Julia. Julia, fearful that her little sister will impair her success on the marriage market, forces Madge to dress as a child of ten. Julia has her sights set on the Earl of Larsdale, but after a series of misadventures, Madge elopes with the young man who turns out not to be an earl at all, but a prosperous young American who is holding her father's notes. Thus, she saves the day for the Flower family.
