text:  Ali Rodriguez, an attendee from Costa Mesa, California, explains to me the concept of cosplay. Why did you come to VidCon? I came last year and it was really fun, so I decided to come again. What do you like about it? I get to meet different creators and I get to waste my money on stuff. And I also get to dress up. One of the excuses is to cosplay. And I really enjoy doing that. Explain that to someone who doesn't understand what cosplay is and why you would dress up.
