That's a great idea. Where do you find out about these events? Is there a website that all these cosplayers gather? I need to get my creep on..
Go to meetup.com and there is probably an anime or cosplay group by you. I don't know if meetup.com does AU though.
I go to the ones in Anaheim, LA and San Jose.
I'll try to get to some other cities soon. Those are the big ones though.
NY has some big ones. Then Japan of course.
Considering the guys that go are nerdy as fuck, your chances of getting a nice cos play chick are pretty good.
