I think I may have come up with a possible solution for the coverall problem:
Get coveralls that look close enough to the originals as far as style and color, then have the sent to someone who can Taylor, rehaul and weather them to look like how they did in the 1978 movie.
That shouldn’t be difficult. I mean, there’s a woman who makes screen accurate Freddy Krueger sweaters, there has to be someone who can taylor Michael Myers coveralls.
haha I just posted a forum like this, but for the Rob Zombie coveralls 
Working on it, lol. I have an orignal pair and they’re coming along. I’ve got the company, worked out the issues, now we’re just nailing the color before full production.
Keep us updated on this! I’m really eager to see how they turn out!
Wow, I totally forgot that I made this thread.
Great to hear everything is back on track! I know I’m late to the party but I’d definitely be interested in a pair once they’re done. Appreciate you doing this for the community. You’re doing the lord’s work for us coverall perfectionists
