Almost every time we make a cosplay post here on Kotaku, the questions come out. Why are these grown men and women playing dress-ups? Why are these women (and sometimes men) walking around showing so much skin?
Those people are missing the point of why people get into cosplay. A point this video explains quite nicely.
It is, in a lot of ways, just like people wearing the jerseys of their favourite sporting team, or a black t-shirt with the logo of their favourite band across the front. It just takes a lot more work.
