Welcome to Susan's Place. While a larger hip bone is nice, much of a woman's shape comes from fat on the butt and on the upper legged. My largest measurement below the waist is at the crotch and much of that was put on as the result of HRT. A secondary consideration is often if you are not overweight, you can lose fat at the wast making you hips look bigger relative to the rest of your body. This process takes time and it may take several years to see the final results.
