Vanessa Williams looked lovely in Lanvin at the 36th annual March of Dimes Beauty Ball on April 11 in NYC.

As the celebrity host of the fete, Williams chose a drapey, pleated number from Alber Elbaz's Spring 2010 collection. Not only do we adore this dress because of it's asymmetrical cut and elegant details, but we also love that it looks good on any woman, despite age or size.

Check out Natalie Portman -- pre-baby bump -- rocking the same dress in purple at an event in November. Surprisingly, both actresses added matching strapy sandals to their gowns -- Williams opting for a black platform pair.

The 48-year-old "Desperate Housewives" star rounded out her look with pink drop earrings and diamond bracelet.

Williams' makeup was absolutely glowing: her khol-rimmed eyes and cinnamon lip color were a perfect balance.

Meanwhile, Lanvin is quickly becoming a red carpet favorite among leading ladies, take a look at who wore the French house's designs just last week.
