Florence apparently does not take this very seriously, but others did. While she was chosen by vote, apparently her biometrics very closely approximate those of the ideal female face according to scientists.
More recently, these five celebrities were the first five rated as the most ideally attractive woman: Natalie Portman, Scarlett Johansson, Taylor Swift, Kendall Jenner, and Keira Knightley.
So what specifics contribute to the ideal feminine face? The person having a heart-shaped face, almond-shaped eyes, arched eyebrows, a small, slim nose, and full lips. Apparently hair color and height are not as important. I have no idea how this research was funded but it could have applications.
