*IMPORTANT NOTE* Yes, I know some of the outfits are wrong. I drew this in a class when I had no way to look up references, and it's been a while since I've watched avatar. Now that that's out of the way...
I drew this in class over the year and, as I was flipping through a notebook on a break from dress making, I found this all ready to go. So I thought that I should give you guys something to tie you out until after the wedding ^_^
It was a random idea: What if some Hetalia characters cosplayed Avatar characters? I think it worked out really well, characterization-wise. Again, apologies for the lack of correct costuming. We'll just go with some of the Hetalia characters are lazy costume makers, k? ^_^
Italy: Ty Lee
Rome: Uncle Iroh
EDIT: France as Haru should be especially funny if you've seen Avatar the abridged series. Go watch it if you're an avatar fan! it's hilarious!
(Neither Hetalia nor Avatar are mine, obviously)
