Er, sorta. Except they sometimes look only a little like the actual character's outfit, and sometimes they only have little tweaks, like yours. But usually they're pretty intracate.
Usually on these, the tweaks are not made for safety or convienence, but more for originality. This is somthing that's really popular in Japan. Since there's so much cosplay going on over there, people get tired of seeing the same old characters over and over again.
So, they improvise. ^_^
