Our Mrs. McChesney (1918)

Mrs. Emma McChesney is a determined and successful traveling saleswoman for T. A. Buck's Featherbloom Petticoat Company. When Buck dies and his son, T. A. Buck, Jr., takes charge, the company suffers and Emma nearly accepts a job offer from Buck's rival, Abel Fromkin. On her last sales trip, however, she learns that her son Jack has married chorus girl Vera Sherwood, and because Buck demonstrates such concern for the boy, Emma decides to remain with him. Distraught that Jack has married so young, Emma sends the bride away to boarding school while Jack takes a job with the company. Later Emma discovers that the firm is approaching bankruptcy, so she invents a new skirt which, as modeled by Vera and promoted by Jack, rocks the fashion world and saves Buck's company. Having fallen in love with Emma, Buck proposes and she accepts.
