Most Helpful Girl
Completely depends on the girl. I know many beautiful women who have beautiful personalities and I also know beautiful women who are mean and ugly on the inside too. Personally, I think the personality of a woman is more dependent on her upbringing. If she was a spoiled brat who was given everything she wanted, she'll probably grow up to be a bitch, regardless of how she looks. And if she happens to look good (which spoiled girls tend to for some reason), she gets even more validation from boys and society that she's the best and can have whatever she wants.
Women that had a more structured home life with boundaries will probably have better personalities later, regardless of how she looks.
