Michelle Obama appeared at the White House Correspondents' Dinner (otherwise known as "nerd prom") tonight, May 3, 2014, looking absolutely flawless in a Marchesa gown. This isn't the first time the FLOTUS has donned Marchesa -- last we saw her wearing the designer was at the Kennedy Center Honors in December 2013.

The white, off-the-shoulder creation was stunning on the First Lady -- but really, do we expect anything less from Michelle? A flowing skirt and embroidered bodice lent to the ethereal look of the gown, and Michelle accessorized with a pair of statement earrings and low heels. Her hair, highlighted and feathered, looked quite pretty as well, if we do say so ourselves.

As always, the First Lady killed it. Click through the gallery to see more of FLOTUS' look at the White House Correspondents' Dinner 2014.
