Yes, they do. Tall people make more money and are more successful in the workplace [1]. Wearing higher-class clothing elicits more responsiveness and lowers the perceived social status of others [2]. And of course, leadership is associated with being white and male, which leads to better responsiveness in work-type environments to white males [3]. I also seem to recall a talk by a professor at Berkeley showing that having some gray hair and wearing glasses commands more respect as well, though I can't find the research to back that up at the moment.
