Style Me Saturday: Casual but Sophisticated

Nicole is attending an engagement party this weekend that was listed as "cocktail attire" but the invitation itself was pretty informal. She purchased the Nanette Lepore Latin Lover dress and Aldo Filby shoes but wanted some accessory ideas on how to keep it somewhat informal but still sophisticated. Here is her outfit without accessories, and some suggestions below (click on any photo for more info). I would keep the accessories simple, and just choose one item (earrings or bracelet or ring).
