Fashion's Mirror (1930)

His father thinks that their high fashion house is failing because his son,Jack Thompson, is spending too much time with showgirl Barbara Newberry. However, it's she who comes up with the idea of offering a musical fashion show and not going to the casino

Fashion shows were occasional features in movies - particularly in color -- for many a year. Even if they wound up dating the movie, they offered the ladies in the audience a chance to look at some lovely clothes. This blackand-white short is more of a musical comedy number, including a line of tap-dancing chorines dressed like Cavaliers, and Pert Kelton in a wedding gown singing.
