Re: beautiful women treated terribly by other women - I know that's what happens most of the time, but I have two examples from high school that kinda don't fit the mold, just wanted to share.
Context: I went to a boarding school with about 450 students a year as a whole (freshmen+juniors+seniors), it's one of the most closed societies ever. You get to know like 80% of what happened even if you happen to be like me (somewhere between socially awkward and unintentionally antisocial), and gossip travels fast.
- There was an abnormal number of pretty girls in my graduating class, really, you could list off at least 10 who were almost universally agreed to be good-looking. None of them had whispered bad words behind their backs or shady glances thrown at them, at least not because of their looks (for instance, one girl got complaints that she was messy, which she objectively was) among us (the girls of our graduating class). One girl got bad word of mouth from the upperclassmen girls, but that kinda had to do more with her entanglement with a known upperclassman playboy than her having doe-brown eyes, great hair, and fair skin. My best friend's and my speculation was that because you couldn't because avoid being friends with all the pretty girls, even if you wanted to be 'jealous' about one of them you kinda couldn't do it out loud. Come to think of it, the boys were way more often bad-mouthing the pretty girls for reasons I don't want to think about.
- Our direct upperclassmen (as in, the kids that graduated the year before we did) had an official 'most beautiful' girl, and she truly was beautiful. Seriously, she looked good at 6 am, yawning, with bags under her eyes. On top of that, she did know she was beautiful (and so did not annoy everyone by saying 'nah' to every compliment) but never flaunted it. As a result, nobody kinda dared to be 'jealous' of her, she was untouchable in that direction. The nice-looking girls of that class did have some issues (one infamous case even got the attention of a teacher), but never her. Her only boyfriend during her high school years got a lot of flack for being, um, unflattering in the looks department, I recall.
