Nerdy glasses. I had a hipster ask for my BCs from when I was in Navy boot camp. I'm sorry, but those glasses have a reputation for being horrendously ugly, since when did they become a fashion statement?
Not me, btw. But here's a picture of what the glasses look like:

Oh, and also dressing in wool hats and leg warmers and wearing layers when it's 90 degrees outside. That's just weird.
