Christina Ricci gives us a lesson on how to be subtly sexy at the the opening of Barneys at The Palazzo Resort Hotel Casino. Her navy silk dress would be conservative if it weren't for that plunging keyhole neck and gold medallion necklace. The rest is simple and sleek, so I threw in a couple items to help complete the look. Does anyone else wish we saw more of Ms. Ricci?! Especially if she's looking this good?
