Diane Kruger's black lace dress — with a high neckline, elbow-length sleeves, and long hemline — sounds conservative on paper, but in reality it was one of the sexiest of the entire night. The lace was totally sheer over most of her legs and on her stomach and arms, flashing a lot of skin without exactly revealing anything.
It might be a little too much to wear in real life, but a tamer version is totally acceptable for your next cocktail party or formal event. Shop the 10 that caught our eyes (including one that's just $30!).
