Okay here I go this has been bugging me for ages.
Cosplay stands for costume play, right?
So, why when it comes to anime costumes people say they are going to cosplay, but when it comes to regular Halloween costumes they calling it dressing up?
For me its called cosplay because you are playing a role and it fits all categories. If you dress up as Micheal Myers you are still cosplaying, you are playing the role of another character.
Could someone help me understand this concept? The difference, I guess you could put it that way.
