I don't agree that these girls look like coat-racks. There is a difference between maximal beauty at 19 and at 30 and at forty. The pageant contestants are all around 18-20, so they're going to be more slender. It's natural for a woman to put on some weight as she gets older, and a girl who is heavier when she's young is going to get fairly porky as she gets into middle age. These girls will all be curvier as they go through their twenties and start to have babies.
As for not knowing what I'm talking about: I have a woman's body, and considering the amount of time I've spent in women's locker rooms, I'd bet my next house payment that I've seen more naked women than you have. :-)
We need photos to be sure! Just a couple would suffice...
