What makes a overweight woman so attractive?

I'm not a male. But a little flesh on your bones shows your fertile and more fat can be good for giving birth, I guess? It gives more energy to the child and shows that the female is capable to feed a baby. I mean, I guess being super overweight only makes you look unhealthy. But having curves and stuff probably shows that the woman is fertile. If your skinny you're probably not as capable to feed children and give birth. Just my thought.
