Hi, im currently investing in H2 Dream Sequence cosplay, this would be my first, but i was curious how I weather the coveralls. I see a lot of people explaining how to weather the original coveralls but not the RZ ones, if anyone could help itd be greatly appreciated 
Just copy the original method and add fake blood
if theyre brand new looking, remove the puffy lining by turning it inside out and cutting by the seams.
Sand the knees, elbows, cuffs etc with 150 grit sandpaper.
After that soak them in a dyebath, use half a bottle of “Rit dyemore - chocolate brown”
and a little less than half a bottle of “Rit dyemore - Frost grey”
that will make them look grubby,faded,worn in. for more weathering like oil/grease stains,
use tulip brand black fabric paint, put some in a cup 1/3rd water 2/3rds paint. then dry-brush it onto the
knees, pantlegs, elbows etc. then perma-blood for the gore
