People about Cosplay...
Absolutely not! There are exceptions, but even seasoned cosplayers who enjoy the crafting side of things will often buy parts of their costume. There’s an entire segment of the community that does commission work who wouldn’t have any business at all without the parts of the community who find skipping to the dressing up stage to be most fulfilling.
So long as you are having a good time and participating ethically (not taking credit for a costume someone else made, for example), you are doing cosplay exactly right!
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.
I was always fascinated with cosplay and always wondered the reasoning behind it. Then last year I decided to try it out myself and see what I would think about it. I was completely surprised by the amount of anticipation I had for one making my own costume and two showing it off.
I think I’m officially hooked on cosplaying because it’s just so much fun to do! The whole process of picking who you are going to be, planning out the costume and then wearing it is exciting! It kind of takes you out of your life and you transform into this other person for that day.
Another fun thing is that many other people enjoy your cosplay. This is usually their opportunity to see their characters in real life, I can’t say how many drive by hugs I have gotten and many refer to your characters name (which always catches me off guard). For that day you receive a lot of love from others and I think that’s usually what makes people want to do it again (at least for me), life has too many unhappy things so being able to create this happiness not only for yourself, but for others as well is a good feeling.
