It wouldn't be a convention without people in costumes, most of which are some variation of cleavage and bare midriffs. Here's a video of some of the contestants for the BlizzCon 2008 Costume Contest, and below is the winner, Amanda Hosler, showing off her creation before the thunderous roar of the approving crowd.
However, isn't she sort of cheating? That's no costume. That's a float! In this interview with World of Warcraft site Allakhazam, Hosler explains that the turtle was built using an electric wheelchair as a chassis. She also reveals the sacrifices she had to make.
Hosler was also the winner of the 2007 contest.
