I think the media gets everything completely wrong.
I am 100% sure most guys find girls like Robyn Lawley:
and Christina Hendricks:
Incredibly attractive. I know I do. TV would make you presume otherwise, but they're wrong. It's so unfortunate that curvier girls get down on themselves and make themselves look frumpy, which the frumpiness is the only reason they look unattractive. Doll yourself up and guys will go nuts over curves.
But, on the other end of the spectrum, I find slim girls (as a simple example, Karlie Kloss) pretty attractive too:
But, if you're going for ideal, athletic really is best. Maria Sharapova is a good example of that. It's physically impossible to win and be unhealthy.
Or, how Maria Menounos was looking at in DWTS:
In the end, it's all different per guy, but we typically like a broader range than what you've probably been told. Just go for being healthy, don't be frumpy and you'll be FINE.
