Unfortunately, there is no magic trick to stop your necklace moving around on your neck, but when you style with LAYERED necklaces, there is one trick that can help to reduce it. Watch the video, try it and let me know if it works. Simply, a chunkier,  heavier pendant will hold it down and because the two necklaces are connected together, it's harder to move around and so you can avoid instances like in the photo below where the clasp moves to the front.  Hope it all makes sense. 

Also, extra tip! 

When you buy a small delicate necklace, see if the pendant is heavier than the clasp, and try to buy one that is if you can. When the clasp is heavier than the pendant, it is more likely to move and come around your neck to stay in front rather than at the back of your neck.
