First of all, I think everyone has their own hobbies, because cosplay is also one of our interests, as long as we don't do anything that violates the law. Just like some people like basketball, some people like dancing, and some people like singing, cosplay is the same with them. So cosplay is nothing special, everything is acceptable to us.
Secondly, just because we like this character, just like when we meet someone we like while watching TV, we also have the idea of becoming them. So cosplay is only because we like this character, and then we will imitate it. It is also a tribute to this anime character.
Finally, the general cosplay clothes are very bright, and girls who like cosplay are not too old, so I think these clothes are very nice and look good on them. Who wouldn't like these lovely characters?
In fact, cosplay is not without benefits. It can help us expand our circle of friends, accept many new things and let us know new friends. So, let's not treat cosplay as an alien.
