a lot of sparkle

In a recent interview, I was asked to describe my personal style. I did as best I could: "I am always casual with a touch of prep,  and very relaxed with a little glam. I always mix it up."
I love this look above b/c it's a simple gray sweater and a messy top knot, with a gorgeous necklace. Below are some other necklaces that I think would fit this look just perfectly.
