People about Cosplay...
First of all, cosplay isn’t just about playing dress-up. Cosplay is a whole lot more than that. Good cosplayers will act like the character while in costume or move like the character. Serious cosplayers won’t break character when they’re in costume. It’s a little bit of acting too. But it’s a culture that’s meant to be fun.
You see, cosplay is a couple things. First, it’s a service to the fandom because other people get to essentially see their favorite characters in the flesh for a couple hours. And this is especially true if you really fit the character. But it’s a lot more than that. It’s a chance to be someone else for a little while. When you put on cosplay, you get to leave your life behind for a little while. And for the people who make their own costumes, it’s a chance to not only show off their knowledge of the character, but it allows them to show off their costume skills and say “I made that.”
So, there are a lot of different appeals to doing cosplay. Besides, with all the photos that people take of you in a day, it kind of makes you feel like a celebrity. :)
No, it is perfectly normal to buy a cosplay costume. Even professional cosplayers buy or get the costume made from someone else. However, making your own costume has a different thrill to it.
What is important though, is how you carry the costume and how much fun you’re having while cosplaying.
As for “devaluing someone’s participation” goes, some may feel that your cosplay is superior to them, when they took more efforts. However, it is not supposed to be that way as these things are done for fun.
To me, it’s equally a tribute to the property that I’m making the cosplay from, and the art form.
One could say the same thing of not getting the appeal of creating any media – learning any instrument, painting a picture, writing a book. It’s creation and display – this may not be the same to everyone, but it’s definitely a big part to me. It’s also a way to meet new friends from all walks of life. I’m certain if you looked closer, a lot don’t meet the stereotypes of an overgrown kid. I cosplay with people in the military, aerospace, tech, and all walks of life. Conversely there’s people that do this for a living, myself included.
As someone that enjoys hobbies and media that was formerly shunned for being “too nerdy”, perhaps immediately throwing anyone that takes part in cosplay into the “you’re a man/woman child” box is a bit reductionist, and a little offensive.
