Florida, hands down. Orange and blue. They dress like a blind gay person as the wife would say. They think they look good, but in fact couldn't match if their life depended on it.
UnderDog37, all of those Nike-designed uniforms with the one-sleeve solid color (UF, Va Tech, Oregon) were hideous. I would go with Florida and Oregon as having the ugliest in terms of color scheme.
ANYTHING orange all tie for 1st place as the ugliest. Living in Jax, I have to drive around with blinders on. There's orange EVERYWHERE, makes me want to puke.
