The linked article seems to suggest that rather than "appearance" what's actually meant is "anything non-verbal"? In which case the related english language thing to look for is writings on the importance of the non-verbal aspects of communication, of which there are a lot.

I don't understand the usefulness or significance (and wouldn't have expected it to be permitted regardless). https://ja.wikipedia.org/wiki/%E5%AE%B9%E5%A7%BF https://ja.wikipedia.org/wiki/%E5%AE%B9%E5%A7%BF
