Hope i could help!!

Answer:
I don't have a specific suggestion for you as for what to wear in particular, but I must advise to not wear a necklace with that kind of dress, dangling black earrings and a chunky black bracelet would look great. (Nice dress!)
Answer:
I think a black beaded necklace would match great.

Like that…and not a long one. :D

Answer:
That dress is gorgeous, I'm jealous. I'd wear a easy necklace, maybe just a black necklace with one stone in the middle. Have fun wearing your dress!
