Layering necklaces has taken a step back this year. Rather than layering with too many over-powering elements, people are choosing to utilize only 2 to 3 specific pieces. This type of layering still creates a unified neckline look without taking over the entire outfit. It also allows you to show-off a specific stone or color with accompanying delicate pieces.
No matter what type of layered look you ultimately choose, selecting complimentary items is key. This includes looking at the individual components of each piece to determine if they work well together. For instance, pairing a colorful and chunky statement necklace (like this or this) with a more delicate piece often results in a gorgeous contrasting look. The accompanying guide features a number of great layering options for the various looks in your day-to-day life.
