..... The wedding is very formal, isn't it? If you like COSPLAY, you can't wear COS clothes? Even if the clothing is not so exaggerated, it can be seen at a glance that it is used by COS.

Unless the newlyweds at the wedding are also COSPLAY NC fans and the two old people are more open-minded, otherwise ... to put it bluntly, I think even if you are not kicked out, people's faces will not look good.

Either your COS character is dressed very ordinary, or I advise you not to. If COS is a comic book, you can wear it in private, and others don't have to wear it at the wedding.
