The belt that comes with the suit is two pathetic sad sad pieces of ABS plastic which does nothing apart from make you look like a right prat (and is not movie accurate). So I got some leather from Tokyu Hands for about 5000 yen and made my own. I was really annoyed that I had to actually pay for leather - back at
my dads studio I could nick all the leather I want! This is what many troopers do (make belts - not steal leather from dad) and you dont have to screw the belt on like the ABS belt.
