Georgina Chapman, who dressed the First Lady for the White House state dinner, was also in attendance for the grand event.

Looking gorgeous is a daily occurrence for Georgina, but she looked especially beautiful on this occasion wearing a gown from her Spring 2012 collection.

On the runway, this embellished gown doesn’t excite in grey, but in blue it is breathtaking.

A bejewelled Marchesa clutch and silver jewels completed her look.

Georgina’s in her element. She’s simply radiant here.
