I think that we should all be celebrating the change from this:
to the suits and ties and whatever. It may still look silly in the eyes of SFers, but it's vastly better than the eyesore that is pants to the knees and shirts to the ankles. As much as I like baggy jeans, I draw the line at not wearing a belt. It also seems to be catching on with the more fashion-aware inner-city kids I know: polo shirts, button downs, a more fitted and sleeker look.
