Quick questions about the tag ainu_clothes.

Should the tag be an alias to, or implicate japanese_clothes?
The only characters I know of that would use it are Nakoruru (and her dark personae Rera & Murasaki Nakoruru, Rimururu and their associates.

I would say no. If they are visually distinct enough to tag separately, they ought to be able to be independently searched for.

Perhaps implicating them to traditional_clothes as an umbrella tag would make sense though (one could also add things like chinese_clothes, vietnamese_dress, etc to it.

Will implicate traditional_clothes
