I scanned the cosplay rules from the Comiket 74 catalog, since the post that started the thread was from a couple years ago. Maybe someone will translate this for us. *puppy-dog eyes* I have about a kindergarten level reading comprehension, so I am missing the important stuff. (I can read Yotsuba&! because of the furigana for every kanji, but far from reading a japanese newspaper)
If nothing else, this should help those that can read japanese to see what differences there are to the rules from past CMs.
