This one is hard for me because I'm bollocks when it comes to picking out younger PBs.
I'm looking for a girl who is either a teenager or could pass for one, so anywhere in the 17-25 range that could still conceivably look like a junior/senior in high school (I guess we're talking CW style, where they're actually way old, but...yeah). No preference for hair/eye color, although she's likely Caucasian -- the most important thing is that she's a tomboy, or at least is athletic, competitive, and hasn't quite gotten the idea that she's grown up and turned into a girl. Which is not to say that she can't clean up nicely, but she looks like she can handle herself (or thinks she can), and misses playing rugby like she used to. Probably not a model, considering they're built like twigs. Halp, please?
