Awesome, thanks! My other half certainly went through enough for it! xD
The coat is actually Frankensteined from two separate canvas trench coats, and then painted. I had to make the mantle for it, and switch the buttons from "female" to "male" configuration ('cos gawd knows Rorschach wouldn't tolerate wearing a women's coat, hurm), and I had to lengthen the belt. Then I sponged layers of acrylic paint on for toning, and then sponged Mod-Podged over the whole thing for depth/shine. The end result is a bit stiffer (and stickier!) than I might like, but it does all right.
(I do have another trench coat from a thrift store that's 90% the right look, though, if you're looking--?)
