WHY THIS WORKS: For a longer length, chunkiness is key: Anything lightweight will bounce around, and anything too dainty will fall into your cleavage. The tangle of crystals and beads here stays put perfectly.
WHY THIS WORKS: If you prefer a shorter necklace, make sure it sits well below the collarbone. An oval shape draws the eye in to create a slimming effect and brings attention up and away from the cleavage.
