What is sexy?

How would you define sexy? Is it the catwalk inspired definition that is being thin?

I remembered reading before the interview of Jennifer Lopez from the Reader's Digest. She said that if she sees two women walking, one is thin and the other voluptuous, she would look at how they carry themselves. The thin girl walks shyly unsure and unconfident of herself while the other walks with grace and certainty enjoying the sway of her hips and the feel of her hair with her head up, without doubts, the latter defines what is sexy.

While the world is succumb by the problems of eating disorders or anorexia, I think it is time to re-evaluate the real meaning of the word "sexy".

By the way, is J.Lo thin? And isn't she sexy?

What is your own definition of sexiness, girls?
