I don't find it really shocking that young women who are fit and reasonably attractive like to show off their bodies. She did dress conservatively during the show and I would also assume that is how she dresses for work. During her free time she should dress how she pleases, within reason. There is also a two-facedness I have noticed in our American society. Popular culture seems to demand that young people be non-prudes and sexually active, while the educational and work culture seems to demand that that they be pillars of self-discipline. Can you blame them if they seem to be confused in their mannerisms and behavior?
Did you notice how the movie " American Pie " which celebrated sexual perversity of the highest order became " American Wedding " which celebrated family values? No wonder a lot of young people are confused.
