Some of the best World of Warcraft cosplays I've seen for a while

I'm not sure were theese pictures are from, but seeing the elf was at didn't make her wear pants, I'll guess it's DragonCon. DragonCon is the only place I know off that allows you to wear stuff like this, as well as just body paint.

Also it's likely she is with a costuming company/contract who have special permission from conventions to be less clothed. They have those rules in place so floods of naked people in 'costumes' do not show up. They wanna make sure the naked comes with a quality costume.
