Petchymon: Awesome cosplay! And pretty cool that the beard is real. XD The black gloves/gun on a black background make the first picture a bit hard to see though... Or it could just be my monitor. ^^;
I had the opposite problem as you with the uniform... My Woodland Camo stuff didn't fit, so I had to wear Olive Drab.
Unfortunately, I can't give any suggestions on Snake's gloves, haven't played MGS1 in a while so I forget what they look like.
