I’ve got a question for all those commenting to the effect of, “These chicks only dress up for attention [which you actually don’t know but let’s roll with it for now], they don’t REALLY care about comics, and that makes them terrible, awful human beings!”
Why do you care? Seriously? Does their existence somehow diminish the source material? At least religious people who get pissed off about others not being as into their religions have the excuse that they think God will be mad and smite them; what possible reason can you have for being so virulently upset that someone who isn’t a “true fan” (as defined by you, of course) wants to walk around in a costume for a few hours?
