How can I make a Black Rider costume without armor?

[mordor]

The Black Riders are probably the coolest character in LOTR. I want to make a costume of one. I am going to use gloves for gauntlets, but I'd appreciate it if anyone could give me some tips. :*)

Well, you get a black blanket. And then you wear it.

Uh, that's about all I can come up with right now.
