Because I'm a social scientist and stuff like this interests me, I will throw out the possibility that geographical and job factors might also contribute to the attitudes toward shorts. I'm 43, female, live in the icebox that is northwestern Pennsylvania, and teach at a college that has no dress code for faculty (some of my coworkers think this give them permission to look homeless or like they're going to the beach). If it's hot, I will wear shorts on stage and during summer school. If I were still living in Texas, I'd probably wear them most of the year.
