It just sounds like you are a flashy dresser (alligator is a little out there). Granted, most college students aren't wearing Kiton, but most probably wouldn't know it if they saw it so I'm not sure that's any indication.
There are better and worse dressed students at my institution. Some dress very well, most dress the way you describe. The thing is, no one unduly notices the well dressed ones. They might get a compliment here or there but there is no peculiar attention made to them. Heck, some of the student body dressed in fairy tale inspired goth clothing (interesting indeed) and even they barely get noticed. Something tells me there is more to this than you are saying. Yes?
