Manners for Missionaries 3: "Appearance and Social Skills" (1994)

This video is aimed at teaching etiquette to everyone but is aimed primarily at full-time LDS missionaries. While not an official production of either Brigham Young University or the LDS Church, the creators were faculty and instructors for both BYU and the Provo MTC, and the film has been shown at many missions through the world over the past two decades.
This segment covers how to dress and interact with others.
