This halter jumpsuit from designer ABS ($290) is a polished one-piece design, tailored with a chic halter-tie neckline and a flattering, flared-leg silhouette. This jumpsuit caught our eye because it is both elegant and sexy. Wear a shoe with a tall thin heel like the Manolo Blahnik “Chaos” sandal. Add an emerald cocktail ring, simple gold bangle bracelets, and diamond stud earrings. This is a situation where pants are better than a dress.
