Let's see...
Juggalo make-up. Most Tripp/Bondage pants. Crocs...I can let this slide if you work in a hospital, as they are easy to disinfect, but other than that...just no. Poorly blended make-up. Neatly ripped tights/stockings...I just want to take a fork to them and do some of my handy-work. Eyeliner drawn ALL over one's face. Most scene-kid fashion. Scrubs with cartoon characters on them (unless you work in family practice/pediatrics). Shirts that say things like "Punk Rock Princess" or "Hottie" or "Your boyfriend thinks I'm hot".
And this....I love my parents dearly, BUT...My father has the tendency to put on the first clean shirt that he finds upon waking up. Right now, as I write this, my father is wearing a Marilyn Manson shirt that an ex-boyfriend left in my possession. Why does this bother me? In big, bold writing, "I AM THE GOD OF FUCK" is on the back of this shirt. I doubt my father even knows it's there...
And yes, while I HATE the sagging pants thing, it's very stupid to arrest someone over that. I do recall a few years ago that some designer actually made jeans with built in boxers to convey the whole sagging-effect.
