I can't imagine why ANYone would aspire to be skinny (no curves, no hips, very small breasts, just rail thin.) I know some people are like this naturally so bashing being skinny isn't cool, any more than bashing being fat is, but the OP asked, and IMO I would NOT want to be skinny...
I also don't understand how anyone can possibly be happy with being fat/obese either. It doesn't look good and it isn't healthy. I don't believe anyone who is fat is happy. I mean actually fat, like 4-5 stone overweight or more. Not the Mumsnet fat where you're fat if you're over a size 10, or more than 9 and a half stone. 🙄 I also struggle to understand how being skinny can make anyone happy, because the skinny people I know/have ever known rarely eat, and are constantly watching every single morsel that passes through their lips.
Me personally, I would much rather be curvy than skinny.
I would hate to look like the woman in pic 1 here OR the woman in pic 3. The woman in pic 2 (in the black bikini) has the perfect figure IMO. Fortunately for me, the woman in pic 2 (in the black bikini) is the closest to what my body is like, and I am very happy with it. I could maybe do with losing 10 pounds, but I'll do for now.
