Which procedure would help me achieve more rounded hips? (photos)

In my opinion your are a great candidate for a BBL. I say this because you have a good underlying shape, not a lot of visceral fat, a naturally small waist and a disproportionate amount of fat in your love handles. I actually call this the 'winning combination' because it makes people very good candidates for a BBL when they have this combination of features.

A BBL would fill in the hip dips and round your butt and blend it into your legs and make it match your body while at the same time revealing your naturally small waist.

You may benefit from two procedures. One to narrow your waist, and the other to fill in your hip dips. Liposuction of the flanks and lower back will create a narrower waist in your case. You can utilize the fat to augment the hip dip areas or utilize hip implants. You don't need a lot of hip augmentation. The combination of the narrowing of your waist with the small augmentation of your hips will create a significant improvement.
