In your photos., the pearls look fabulous whichever way they are worn (oh, to have your model's looks.....
).
I'm currently putting together a slightly longer rope - smaller pearls, about 6mm. - 7.5mm. - and will wear it layered, layered, layered...
Sometimes wrapped three times, sometimes four, sometimes more.
Depending on how I feel and the occasion.
I deliberately chose smaller pearls so's the rope won't feel too heavy.
I often use brooches as enhancers, too.
