Need curvy hips? Help me!?

I desperately need wide, womanly hips. I have a nice, round, medium sized bottom however I feel like my body shape is thrown off by my slender hips. Having bigger hips would make me look fleshier and older. Basically from the front I look straight up and down but from the side I look curvy. I am naturally petite and slim and 17, meaning puberty is over for me. I currently do squats and lunges every other day. Any other secrets/tips?
