They can make or break an outfit. If it works, adding some chunky bangles or a statement necklace to a simple LBD can have your rocking it, though over do the Goldie-Looking-Chain and you could be rocking a more Chav-Queen-Essex-Reem look than fashion A-lister.
Now, don't get me wrong, I'm all for layering up the necklaces, but it's all dependant on the look you're going for! A dress with a beautiful embellished neckline for example, needs no touching up. A shirt with a quirky studded Peter Pan collar requires no additional neck accessory, yet try rocking a simple LBD.. LRD.. LWD.. any L_D and you'll feel a little naked without some sort of neck/wrist/finger attire!
