GenCon 2011 was a mass of costumes from every area of pop culture. Video games, movies, anime, RPGs, and comic characters brushed shoulders with tens of thousands of attendees.

While there were a few definite trends (Steampunk, Homestuck, schoolgirls, kilts), it was impossible to capture more than a fraction of the awesome cosplayers. Here are some of our favorite costumes from this year.

Chainmail bikini, fantastic for protection!
