Peasant clothes are the best!
You will not get respect from your teammates, but your enemies will underestimate you, granting you that extra edge that gets them killed. Going with a shirt, round buckler and any sword is just extra fun, hardly anyone expects the punch that you are carrying. Of course, half a mistake and you are done, but it is so fun...
Also, fake peasants scare me more than any one of the kuyak clones. Why? Because I know what to expect when I approach a "standardly dressed" guy, but that other one in drapes, with a small club, meh, that is easy, right? RIGHT?!?! I am now knocked down and dead before I even realise he is not what I thought!
