mortal kombat

My buddy and I are going as Scorpion and Sub-Zero (from Mortal Kombat) for Halloween. I'm Sub-Zero and if I can't make fog come out of my mouth on demand it just won't be the same (you know, like it's cold. C'mon, keep up.) So I did some searching online and all I can find are a bunch of idiots...

What can I say. Smoke is way bad ass this year so I wanted to do a costume of him. My biggest problem is the chest design. Any ideas people? also if you guys know where I might be able to purchase a wig like his or I could buy a regular wig and cut the hair to look like his.
