Maybe you share our affection for well-defined curves like those of the wasp-waisted women in vintage Avedon photos. The cinched waist has great, iconic power, and—hooray!—it’s one of this season’s must-have looks. Lucky Ms. S., you’re already a natural fit for waist-defining styles, but to further refine your curves, may we suggest a cut-in neckline? It will create an upward arc that will visually widen your shoulders; if you mix it with a flared skirt, your middle will appear even slimmer by comparison. And, like Wonder Woman, we believe that a wide belt provides a bold finish.
