It's International Cosplay Day! What better way to celebrate than with some creative inspiration from Comic-Con, where it's the ultimate expression of fandom. The word "cosplay" is short for "costume play," and at conventions across the globe, cosplayers attend in elaborate ensembles resembling their favorite comic and sci-fi characters. Some of the more imaginative cosplay enthusiasts even create their own fantastical personas.
