Emily is that a 16" chain in your new avatar? I would go with something a little thinner in thickness and an 18" chain. The reason is because I want the V shape of the chain to hang downwards a little longer to balance the length of your face. It will balance what I call the "ice cream on top of the sugar cone effect" better. Like as it is, it's too ice cream top heavy. you know what I mean? yeah sounds weird...

And a little thinner because you want it to gracefully accent you, and not be too bold. That's what I try to do when wearing necklaces.
