i will admit i have always wondered the same thing. i also really don't think Mizore's или Kurumu's outfits signify there monster forms. Yukari's definitly does with the whole witch's hat and cape. I think Kurumu's outfit is the way it is because due to her umm.. traits it reveals еще of her form where as if she were wearing the standard uniform it would cover and hide her body еще since there is that куртка like part of the uniform. Also with Mizore's outfit i personally think that еще so shows off her different personality, almost like she is Показ that she is not part of the majority but is her own unique person and her outfit i think says that about her perfectly. Well that is my best answer for this Вопрос but just like the tootsie pop the world may never know.
