With party invites piling up, I started my quest at Versace. The silver one-shouldered cocktail dress ($2,240) felt so silky that I ignored the asymmetrical neckline—a feature I usually despise. Though the sewn-in thong was slightly shocking, I was blown away by my reflection in the mirror; the diagonal ribbing and high slit added curves to my boyish figure. The dress was too sexy for the office bash but great for a fancy date at Jean Georges. 647 Fifth Ave., at 52nd St.; 212-317-0224.
