Pink! Because this is a dress for celebrating in!
Navy all the way with lots of metallics (shoes, bag, accessories) please.
Navy! Tons of pearls a la Angie or a statement necklace (BR has nice ones right now). Nude or metallic shoes. Bag - nude, metallic, cream/winter white, fuschia, yellow? And why not try your silk fuschia BF jacket with it? Who knows? I love BF jackets with dresses.
