On its own, this sophisticated dress (which iVillage Guest EditorAlicia Keys wore to the 2012 Grammys) would be a seriously stylish LBD. But add on an eye-catching statement necklace, and you've got yourself an unforgettable look! Stylist Laura Jones cites this chic ensemble as one of her favorites that she's put together for the singer. "That was our first major red-carpet look together, and she wore a black Alexandre Vauthier figure-hugging dress with a stunning gold shield necklace," she tells iVillage. "The dress played up all of Alicia's best assets and was sleek and modern."
