People about cosplay...
You absolutely do not have to make your own costume to cosplay! Made or bought, cosplay is cosplay. Cosplay is more than making an outfit. It can include makeup, wig styling, and prop making too, besides sewing the costume. Some people, like me, style their own wigs and do their own makeup, but can’t sew or craft. Some people simply wear the costume and don’t make any of it, and that’s fine too. This cosplay elitism needs to stop, of course it isn’t wrong to buy a costume. As long as you’re having fun, you’re doing it right.
Costume play is very powerful tool. Any role play, with or without costume, allows a person to express things with much less risk and responsibility. Through this self exploration proceeds unimpeded, and new behaviors are tested to see if they will be useful.
Constructively used, this allows becoming more oneself and testing of one’s environment and abilities. I allows a person to test revealing things about themselves and see if it meets with rejection, and extend their comfort zones. It allows testing of fears, e.g., permitting a shy person to try being outgoing to see how well it works for them.
On the other hand, a costume, role or disguise also permits a person to enact their worst and most damaging behaviors anonymously. It is far easier to behave badly if one has a costume or role which hides the identity of the person both literally and figuratively.
For me, cosplay is the art of bringing a fictional character to life using yourself as a medium. As people have already mentioned, cosplayers put a lot of money, time, and energy into their craft. Some will go to extremes to lose weight or learn a technique outside their skill level just to try and cosplay that character.
I really love cosplay and I find it is a mirror of how you will treat a lot of things in life, whether that is your job, your relationships, etc. The typical time and project management questions always appear (“Can I finish this in time for this convention?”, “Do I have the resources?”, etc.) but also some that you may not expect (“Should I just stitch this poorly to save time?”, “Will cutting a corner here affect the project later on?”, “Should I invest the time in learning this new technique and apply it to the costume?”). The way you answer these questions are exactly the same way you will answer these questions in real life.
That’s why cosplay is such a great way to make friends than other activities. Not only do you have a great excuse to geek out to like-minded people about your passions, you also can see whether or not they do as they say. You really get to know the people and can truly bond with them.
