Wow! Love the dress! I think you are limited to earrings and bangle due to high neck and pattern. Maybe gold? Or perhaps that's just me looking at this model's colouring. Silver if you're pasty. I'd probably go for large hoops or similar size earrings, personally.
I don't think you need many accessories to be honest. Certainly limited jewellery just a bracket and earrings. Flats or high heels would look good depending on what you feel comfortable in. Oh and on to the color you've answered your own question. God would be gorgeous.
