People about Cosplay...
There are three ways you can go with this:
I recommend starting with the DIY route. There are a plenty of costumes that don’t take much work and can be made by combining everyday items, which are great for beginners. And at the end of the day, it’s your own creation.
- Buy a Halloween costume: This is easy and cheap, but “kit” costumes tend to be poorly made, only available for the most mainstream characters, and pale replicas.
- Buy a cosplay costume: These are usually higher quality and are available for more obscure characters, but tend to be expensive. You’re looking to spend a couple hundred dollars at least.
- Make your own costume: This takes more work, but allows greater creativity. Not only can you make a costume for any character that comes to mind, but you can do fun twists like gender bending (female version of male character, vice versa) or mashups (Darth Batman). The cost can vary depending on how far you go with it.
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.
Putting aside for the moment that the tone of the question doesn’t imply the most open of minds, cosplay is – simply – acting. Do you consider Mel Gibson, Ken Branagh, David Tennant, Cumberbatch, et. al. immature for wanting to dress up and act as Hamlet? Cosplay is a similar – if not identical – mindset: people, inspired by characters, possessing the right combination of talent, bravery and self-awareness, performing as said character for an audience. Whether it’s a convention stage or a Broadway stage makes no difference. The person who portrays Deadpool or Master Chief is very much spiritual kin to the person who plays King Lear or Hamlet. It’s wrong to praise one and denigrate the other based on the source of their inspiration, for to declare which works are “great” and which are not is subjective or worse. Still, even if most consider it blasphemy to compare Marvel to Shakespeare, the motivation to portray characters from either realm is identical and the healthy mindset WON’T criticize this, realizing that whatever it doesn’t “get” is not automatically inferior or invalid.
PS: Ironically you will find, if you but ask, that most cosplayers as children were very successful Trick or Treaters, as Halloween is quite often the “bug” that bites them for their subsequent motivation.
