It seems like most people are tagging the hairstyle of inazuma_(kantai_collection) as simply hair_up but technically that tag is supposed to be for alternate hairstyles. But there doesn't seem to be any existing tags that cover hair folded up and clipped in the back like she has (it's not a ponytail nor a bun). However, I'm actually not even sure what you would call it in real life to make a tag.
Anyone have any ideas?
