And this suggestion came up a long time ago. How about one type of clothing would protect more against zombie bites or scratches. It's pretty obvious that a leather bomber jacket is gonna protect a scratch, maybe even a bite, but a polo shirt isn't. And what if you clothes get so much drenched with zombie blood, it would make your character sad or even drepressed (I can't believe if anyone would like to wear blood coated jeans or t-shirts).
