I added a cosplay mash tag since this outfit is from the doujinshi post #4072017
I also think it's worth adding a tag for this version of the mash outfit something like mash_kyrielight_(yd_(orange_maru)) or the more detailed dancer?, harem_outfit?, since there are enough arts with this version on danbooru
