And it's also classist. On the one hand, you might see a person and think that they look ridiculous, but those clothes might have been the best they had to wear for that occasion. I remember my long-ago ex-girlfriend being nasty and saying that when I told her that I would be wearing a shirt with some purple, she expected that I'd be wearing something like what would be worn to a nightclub. My brother used to go nightclubbing, I have never been nightclubbing, as the noise sensitivity would have driven me crazy.
I like wearing polo shirts and shorts in summer and flannelette shirts and jeans or chinos in winter.
