If we did the whole Halloween thing over here, my preference would be one of the armor sets from Monster Hunter 3 Ultimate. Good quality pictures are hard to come by, but obsoive this gist of an example:
Two things though: A, we
don't do the whole Halloween thing over here, and B, if I was to make an MH3U armor, I'd want to do it as for propers as possible, which means requiring more time and resources than I have now.
Don't get me wrong, I have every intention of making MH3U armor, just not for your excuse-to-wear-a-costume-day.
