Layering necklaces are a fashion trend that has been incredibly glamorized by celebrities like Kim Kardashian and Reese Witherspoon. However, to be in style and to look stylish, you need to match the balance. To make your jewelry layering work for you, keep the thickness of your necklace proportional to the rest of your outfit. And even go for a different texture, like pearls and diamonds. Just remember to keep it wearable: don't pile on too many pieces!
