From my meagre experience:
- Jorts, Crocs, and pants that flood.
- tucking shirts into ridiculously high-rise pants. see: mom jeans
- absurd distressing. Not only is it disingenuous, it shows you have no taste in fashion. Subtle and attractive distressing is one thing, but you've gone overboard when it looks like a tiger scratched your crotch.
Yesterday at school there was an obese girl wearing a fuchsia shirt with jeans that were impossibly distressed down the front and back, like two huge stripes...revealing that the cotton was not an off-white, but, in fact, pink. And of course, her blue-and-pink jeans matched her shirt.
