It is mainly from a bestseller book. You could get hint from this.

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.

Also, why does the linked article (容姿) contain a fully nude image? 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

...have you checked the linked page translation, it's just a page on the concept of physical appearance...

		Yes. I do not understand how an article about physical appearance meaningfully benefits from a nude photo. I thus find myself wondering if the machine translation perhaps lost some important nuance.
