Beauty comes in many forms and can be quite abstract - think of a creature that looks frightening but has fascinating lines with its form flowing in eccentric manners building a kind of "morbid" statue. On the other hand imagine a well proportioned fair and powerful "humanoid" of either sex which pleases the senses in a more positive, soothing manner. Both are in their own way appealing.
What I, and this is of course only MY oppinion, have witnessed though, is that beauty in itself(besides "dark" or "light") has an intrinsic quality of worth that can be felt/sensed.
If somebody wants to "sell you on something/someone" looking beautiful in its own right - feel inside yourself if you sense disgust or approval... and go with this verdict. I have the theory that our genes and energies either accept or dismiss something based on possible nurture or danger.
