Some people like the look of plate and some people like the look of leather or cloth. I think that medium armor classes such as thieves should have some kinds of plate available to them, maybe it could look like thinner metal or have some obviously ranger thing about it but I think this would be really cool for the general experience.
I also think that cloaks would be awesome, cloaks that show through some of whatever you are wearing underneath, with and without hoods.
