Not sure what you mean by grey unless you are referring to the black shirt he has, he used that in the show pretty frequently actually, if you are referring to the blue one he used that one in the dark tournament, as far as the shirtless look the body is here, the torso actually looks nicely done, just hope that the pinholes aren't there in the shoulders but I can't seem to find them in the other pictureswish they show him without the shirts. also when did he wear the grey shirt?
how much pleather are used? looks like the scabbard, top of boots and maybe the white belts are pleather. dont think they use real leather.
