What do people who dress up do for 3 days? Just walk around, pose for pictures, and pretend they're important?
I was actually thinking about something similar today, which is that there are different types of cosplayers. You can tell which kind a person is based on their costume.
The first kind is the Wannabe cosplayer. They dress up because they see the convention as an excuse to and they think it is cool, but they put little to no effort in their costume. More likely than not, they just wear something simple out of their closet that resembles something a popular character would wear. Chances are it was a last minute decision.
The next kind is the Casual Cosplayer. They usually go in groups and collaborate with others on what costumes they should all wear. They usually plan this out a month or two before the convention. Sometimes their costumes are cheap and can be found in the Halloween section of Wal-Mart or Target. They go hoping people will ask them for a picture, but usually leave disappointed.
Next are the Hardcore Cosplayers, also known as, but not limited to, the Anime Cosplayer. Their costumes are usually custom made to a certain extent. Even if its just a regular pair of jeans or shirt, it has custom designs or logos that look, and because of this, it has been in progress many months in advance. And in the case of anime characters, crazy hairstyles and accessories are included. They get stopped every now and then to get photos taken of them.
Finally, there are the professional Cosplayers. More often than not, these people are professional models who have no interest in comics or superheroes, but show up because they look great. Their costumes are entirely custom fit and made, either by themselves or with help from professional tailors. Some are sponsored by agencies and gain more recognition from them. And unfortunately, they are not there to check out any panels. They are simply there to walk around, get mobbed by photographers, and then disappear for a while before being sighted again. Say what you want about them, but they always have the best, most expensive looking costumes and look a lot like their superhero counterpart.
