Xena: Warrior Princess
I'm pretty sure this isn't actually Xena and is likely a character from a video game, but it's essentially irrelevant. The thing with these super-skimpy Comic-Con costumes, as far as I'm concerned, is that they're kind of sad. Dressing up in a sexy costume at a comic book convention so that a bunch of dorks can drool over you (and I'm not even saying that's actually the truth anymore, just that it's obviously the thought process that motivates these girls in their costume selections) is kind of like going down to a middle school b-ball court and blocking a bunch of 12-year olds' shots so that you can feel like Kevin Garnett.
