Because no one understands how to show that a person is considered beautiful in their society's standards, so they settle for making the character beautiful by our society's standards.
And instead of having a character be beautiful outside of what our society generally says, they're a petite blonde haired blue eyed girl who's thin but with big boobs, and it's annoying to see the same base model everywhere. I know in my fae courts, the fae do look human (because humans don't trust things that aren't like them so it's a survival mechanism) but are generally all pretty tall, strong, and have different skin tones and hair colors, etc.
