Well, this is very obviously a closet cosplay, but I don't think it matters in this case, because overalls and a red shirt is what the costume actually is, so I saw no need to make it when I already had everything. This is the outfit Anza/Usagi wears in the Honzonban video, a special fan event for the musicals. I love love love Sera Myu, and have never seen anyone cosplay this before. I love the mop, too.
