With this Ralph Lauren evening gown I would pair this large stone Harry Winston collar, Grace Vanderbilt's luncheon earrings, and a 1960's Harry Winston bracelet.
For a luncheon I would choose this Ralph Lauren ensemble and pair it with a sapphire brooch, bracelet, and a simple strand of Pearls a la Barbara Hutton.
Funny video!!!! I love that Gainsbourg is feeling up Deneuve. Totally hysterical, she grabs his hand and won't let go to stop him from feeling her breasts. http://www.youtube.com/watch?v=PDd7z9cfCgM
