Hourglass bodies are better for girls than guys. Unfortunately, I have that same type of body structure, meaning that my hips line up with my shoulders. Pisses me off. Anyway, it's good for a girl. It creates broader shoulders and hips so that her tummy looks skinny by comparison when she's toned. Being a guy and trying for a V shape is a different story. Toning my obliques and widening my lats isn't enough to make me appear as fit as a guy with a bigger tummy.
An hourglass figure is extremely sexy. Note that most guys don't want the girl to be too thin in the middle or too big on the top or bottom. To have a perfectly proportioned hourglass figure is one of the things most sought after by guys. But every guy does have his own thoughts of beauty.
Hourglass bodies are considered the most attractive. What is not attractive is the weight on the hourglass body. If you are in good shape, then the hourglass in the most attractive. Think of marilyn monroe, Milo d'venus, and all other women who are considered other wordly beautiful, most if not all are hourglasses.
Be happy with what you have. Confidence is the sexiest thing you have overall.
