Wow, I had no idea there was such a thing!
I don't have one, obviously...but I do occasionally wear my dad's old letter jacket from high school because it's so pretty--purple and gold, plus, it's from '57 so it's "vintage!" Other times I wear my boyfriend's letter jacket, but it's bright red and my school's colors are royal blue and white so it looks kind of weird, I'm sure.
I don't want people mistaking me for a Louisville fan or something, God forbid!
