Alpha's, Beta's and Gamma's?

I think the age group is really off for this type of story, but Holly is the closest. Anyone with "greasy" hair isn't alpha material. Alphas maintain their looks and physical attractiveness is very important for that. They don't have "yellow teeth" or wear "saggy clothes" like Katharine. And they don't have "spotty face" and "overcramped wonky teeth". Girls that end up with lots of girls flocking to them become the alpha and girls flock to a confident leader (which is what Holly lacks) who is seemingly "perfect". None of them strike me as an "alpha", but Holly seems best but she needs more confidence because that's what makes a leader. Girls flock to the girl who knows what she's doing (or at least acts like it).
