I saw some videos and websites where they say that feature about changing clothes was supposed to work and have impact when you have a bounty or not and come back to the same town, committed several crimes in specific town and it was supposed determines if witnesses will recognize you or not. But after all it never worked at the game . It would be a nice feature if our clothes,hairs,horse have impact on unknown status or not.
