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!
Let me make it simple for you.
These are some factors which make this fun-filled activity very fascinated.
1) It is Fun
We are all fed up of real life sometimes, the animated world always considered as utopia and we like to experience that Utopian life as the way it is – funny and playful. It is entertaining and enjoyable.
You can express your love for the character which fascinates you. This is the best way to enjoy the fandom of a particular character that you really like it and want to hide your personality under the charm of whatever character.
People like to be a center of attention. Getting compliment on your creativity or catching the eyes of your friends towards famous movie character is always flattering.
We all like creativity, sometimes costumes are crafted by hand. The process includes sewing, cutting, using something completely different thing for entirely different purposes make you proud of cracking the unique idea that nobody ever think of.
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.
