Darth Maul Costume for a Bust

[LDR]

Hi guys, I'm finishing off a Cyberman Darth Maul bust...painting, glass eyes etc.

Anyway, I want to get some reasonably accurate yet cheap clothes, the bust only goes down to the top of the chest, so I would only need the vest/jacket/cloak hood, etc.

So does anyone have an ideas? What should I use? A black karate jacket? Can anyone sell some cheap tatty ones that I can cut the top half off?

Any good cheapish ones on ebay? Or are they all rubbish?

Any suggestions would be much appreciated.

Thanks

Lewis
