I hope you've figured out that you need to share Mary with Nashville, and not just keep her all to yourself.
Remember Kurt Cobain and all those guys from Seattle? They didn't really care about what they wore. They just put on flannel or whatever, and it became the "grunge look". In your case, you wear whatever it is you want to wear so eventually you're going to be a trendsetter. At this point, I would call it the "Americana shorts" look. Perhaps the fashion media would have a better catch phrase.
