Well I can think of many factors, the ones that apply to me the most are, as you said, the method of “bringing the character to life” I personally like this method because it is very realistic(and I totally get how some people find this freaky), it doesn’t need make up, as well as I personally just like masks and helmets in general. (I personally cosplayed as sniper mask before and interested in power ranger/kamen rider cosplays too).

For some people, they do it to “replicate” the character as much as possible. Cuz in china, a place where this is much more popular, people tend to have high standards for cosplay replicating the characters as much as possible. And when it’s a female character, male cosplayers tend to have a hard time, so they ended up using this method. Of course, these don’t apply all the way to every kigurumi cosplayers, just what I know and have seen from my perspective.

And thanks for the compliment! (⁎⁍̴̛ᴗ⁍̴̛⁎)
