J Crew Zig Zag Sequin Dress. If you like this dress you can buy it here.
Since the dress has long sleeves and a high collar, I would probably not wear any jewelry with it. Especially considering that it is sequin, so it is going to be pretty flashy. Instead of accessorizing with jewelry, I would wear a heel with a bit of colour. The African Violet colour is perfect to off set the black and white of the dress. This Licorice pump is Kate Spade and you can buy it here.
