She's stunning. Obviously some guys might prefer a different bodyshape - that's just a matter of personal taste - but she's certainly not so thin that it would have any adverse effect on her health.
And I agree with what you said about curves. People seem to think "curviness" is simply a measure of body fat (or even use it as a euphemism for fat), but it really isn't - it's more about the ratio of waist to hip / bust measurements.
Curvy, having hips, a butt, boobs, etc that aren't straight up and down, they add "curves" to your frame.
I'm pretty thin. I'm about 5'7 and 112lbs. It's physically impossible for me to gain weight though, or else I'd be about 300lbs with how much I eat on a daily basis lol. However I don't really look unhealthy or anything, I just have a small frame. People need to learn the difference between skinny, and unhealthily skinny.
I agree with that guy up there. She looks perfect. Many girls would do anything for a body like that. Although I don't think that that should be the Ideal. It looks great for her, but that doesn't mean everyone should have a body like hers. Everyone is different, but amazing in their own way. ;)
still thin but not so thin that you can see bone...that other is just not healthy looking.
Curvy can have a wide range of definitions actually. some consider it someone with boobs/butt bigger than the waist or some consider it alittle on the chunky side. usually it's a hip to waist ratio thing that defines it but in no way at all would that girl be curvy. not even alittle.
I think you could have posted a pic without the nipples?
Any way, she is real thin. Perfect enough size to be a model, but in the real world she looks fragile very small.
