Wearing a necklace is an elegant way to enhance your decolletage, but opting to wear one should largely depend on the neckline of your dress. As a rule of thumb, your desired piece should sit directly against the skin. High necklines, halternecks and one-shoulder gowns can look cluttered with a necklace layered over the top – let the dress speak for itself. Lower necklines like scoop, square, sweetheart and strapless styles, however, offer the perfect framing for a beautiful rivière or choker, while plunging necklines look best with pendants, drop necklaces and lariats.
