How do I get curvier hips and bigger breast?!

The type of body shape you develop as an adult is 100% depended upon your diet, genes/genetic structure. Look at your mother, sister, grandmother, aunts. Are they shapely? Diet can somewhat help improve a desired figure, and there are natural supplements that are known to increase bust size. The female body doesn't even fully develop until after she reaches 25 years old. You're still young. I'd wait a bit before doing anything. Try certain pectoral exercises. Working the muscle may increase size a bit? Also, mid drift/tummy exercise can slim down the waistline making the hips appear wider and fuller. You can try that. Hope this helped :)
