So, BRTD, what was the case?
Well it appears the answer is "The ones who were hottest in high school mostly didn't show up, but the ones that did aged very well."
I think though that teenagers judge the attractiveness of other teens weighting different factors than 28-year olds do rating other 28-year olds. For example teens might mock a girl who is slightly overweight, even if she looks great otherwise, ten years later this wouldn't be considered as big a deal, or some might just appreciate that she has a more voluptuous look.
