She lost the looks she had when she was a child and a younger teenager. I don't think she looks bad, she's still a very attractive woman. The reason why her looks changed so much is because the bones in her face grew along with her tall body. By her late teens, early twenties, she had already looked a bit different. Her face filled out along with her jawline and gave her a somewhat harder appearance. We all change as we get older, but for her, it seemed a bit more dramatic when it happened, especially considering how soft and pretty her features used to be. Short of shaving down her jawline and the rest of the bones in her face, there really is nothing she can do about it. Not that it would work anyway.
