Your jewelry should coordinate with the fabrics in your clothing. Heavy shell or wooden beads don’t work with a thin silk blouse. You would be better with several thin chains or a strand of pearls. Pearls are not usually shown at their best with heavy denims or tee shirts. Wear those heavier cork or stone beads with your heavy denims or bulky sweaters. Along the same lines, the length of the necklace should coordinate with your collar. A choker can be worn with a very deep neckline, but if you wear it with a turtle neck or high neck shirt, it looks crowded.
