D&D, being a different universe, must have created a different norm for beauty. I mean, if you have elephant people, turtle people, cat people, dragon people, merfolk people, silver skinned people, orange skinned people, green skinned people, robot people, demon people, devil people, bearded women, etc. AND, all these people manage to live together, side by side, with nary a remark about how ugly the others are, then it stands to reason that they have a universal definition of beauty. One that translates across species. Of all the adventure paths and NPCs created by WotC, there is never a character that spouts stuff like: "Those dwarven women are hideous. Kissin' a scratchy beard - gross!" Never a disparaging remark about tails, horns, scales, or cloven feet. So they must have a universal view of beauty. Which, in my opinion, sounds kind of nice.
