People about Cosplay...
To answer your main questions, No and No. Cosplay is supposed to be about inclusiveness, fun, and showing your love for a character.
That being said, as with any group of people, there will be jerks on both sides. There will be those that make their costumes and look down on those that buy them, and vice versa. Jerks can be found at all levels of cosplay, just like regular society. And just like regular society, you have the choice to ignore the jerks and go your own way.
If you are happy with your cosplay, not competing in a 100% bought cosplay and are having fun, that really is all that matters.
People who make their cosplays receive just as many nasty comments and critiques as those that buy them by the way.
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.
I have a rather complicated attitude towards cosplay and cosplayers.
Part of me think of them as rather silly. I mean, grown adult dress up in game/amine/comic book characters with homemade costume, and act like they’re actually the character? Com’on…
But at the same time, I admire their creativity and bravery. Some of the costumes are really ingenious and of high quality! I mean, let’s face it, game/anime/comic book characters often have the most unrealistic physic defying clothing. It takes some real creativity and talent to create it in 3 dimensional reality and to have the killer body to wear it.
Cosplayers are very passionate about their craft, which is something I can relate to and appreciate. If one of those days I can loose 30 lbs, I’ll go dress up too.
