I think clothing can provoke a fight.
A few years ago my wife worked for a bank and the women had to dress professionally, you know skirts and nylons. Well there was a woman she worked with and the 2 of them didn't like each other to a point where they nearly came to blows one day. Anyway, a few weeks later the other woman came to work wearing a skirt and black fishnet pantyhose. My wife thought that it was very inappropriate for her to be wearing fishnets and she said something to her manager. After that I didn't hear anything about the other woman wearing fishnets again.
