When your shoulders and hips are even with a smaller waist
Keep things as comfortably close to your body as you can. Your proportions are optimal so you don't want to do is lose them. Your only rule, stay away from anything boxy. Shapeless styles will make your waist disappear and throw your proportions off, including a-line. For pants, high-waisted and full-lengths work best. Stay away from over-embellished hips, and keep the details to a minimum to keep your proportions.
