But one thing does stand out.

Oriental means eastern, as in from the east in latin. As in things from the orient are from that area of the planet. ( https://translate.google.com/?sl=la&tl=en&text=Oriental&op=translate )

However since the two characters mentioned are from a completely different universe, reality, and most importantly a piece of fiction, where things like that are worn, it's perfectly fine.
