Is there any easy ways to make your waist thinner and hips larger?

These desirable. (for women!) anatomic features are somewhat genetically determined but many have been successful at sculpting their bodies. Follow a well-rounded workout routine and cut fat/calories from diet. Incorporate strength training targeting the "glutes" (gluteus maximus, etc). Reducing your waist size involves toning abdominal muscles and burning fat that is covering them. Engage a personal trainer.
