Demi Moore in Donna Karan LBD at the 2009 Inaguration

Demi's always polished. And seriously — the woman looks better than ever. This week was a whirlwind with the Inauguration and the Sundance Film Festival so we had continuous style stimulation. But sometimes an LBD rules all. Demi looked excellent at MTV's Ball in her strapless, ruffled Donna Karan frock. The wavy bodice and skirt detail are what really make this dress standout; it's such a lively formal option. Talk about a modern classic. Her long brunette locks look fabulously laid back, but her Cartier diamonds keep things black tie. Satin black platform pumps keep things grounded, while her handsome partner in crime continues to be her mancessory of choice.
