The "Wow" Necklace
It takes just one of these to dramatically transform the basics already in your closet.
The Deal (right)
A triumvirate of ceramic flowers in sugar-cookie colors makes for an elegant breastplate that lets you advance fearlessly into a party. Shelly Saber for GS Lillian, $95
The Middle Ground (left)
A medallion embroidered with antique ruby and diamond look-alikes hangs from four jeweled strands and ties on with silk ribbon. Imagine it gleaming at the throat of a (partly unbuttoned) white shirt. Elie Tahari, $398
The High End (top)
This bib necklace is a really big show. A triple row of smoky Swarovski-crystal pearls explodes into a cluster of exuberant satin roses and grapes. Very effective with a fitted black turtleneck. Beavaldes, $670
