Character Model Options

The idea for a game I have would have the main player wearing something along the lines of a cloak/trench coat, but without cloth physics, Im thinking that might be a pain. One idea I have is since it will be a FPS, cloth physics wont matter, but then again it will kill me on the inside knowing that I used that to get out of using something else. So, would anyone agree thats a good idea, or could anyone come up with some other options for what he could use. Thanks!
