Please suggest accessory ideas for this look!

I'm wearing this dress to an evening wedding http://www.bcbg.com/en/clare-s.....CBGMAXAZRI

with these shoes http://www.bcbg.com/en/prue-hi.....A&;

I would love and appreciate any suggestions for accessories: long necklace, handbag, and/or earrings. I purchased the dress and shoes at the sales gal's recommendation, but I need your help to complete the look!

Thank you for reading my post!
