It looks like you could get a black body suit as a base, then modify it (ie, cut the sleeves to make them short like his), unless you can sew. Then I'd start working on all the armour since it seems like there's quite a bit to create. There's lots of great armour tutorials online/youtube. I don't know if this even helps but :P I tried.
