Comic-Con 2013 is over, but here's a roundup of some of the sexiest cosplay costumes at the convention. The biggest nerdgasm of the year boasted plenty of activities and announcements about upcoming movies, games, tv shows, web series, books and, of course, comics.

But half the fun of Comic-Con is the costumes. Cosplay, dressing up, geek Halloween -- whatever you like to call it. Attendees spend the entire year working on their costumes, just to get a chance to parade around as their favorite characters for the weekend.

And some of the costumes were amazing. Whether you like superheroes, zombie survivalists, cartoon mayhem, Disney princesses or sexy femme fatales, every conceivable genre, style and medium was covered. If it has fans, you saw it walking around in full regalia.

It's a way for costume designers to show off their skills and compete, as well as a nice respite for shy fans to let loose for a few days. And it's clear that many people take their costumes very seriously.

Honestly, it's hard to tell what's professionally done and what isn't, who's a paid actor in official gear and who's a superfan with a great eye for detail. Scroll down to see some of the best Comic-Con babes from this year's festival.
