For her husband's final State of the Union address, the First Lady went out on top. Michelle Obama stood out like a beacon of light in the sea of black and navy suits that filled the United States Capitol Building's guest box on Tuesday night.

The ever-fashionable FLOTUS looked stunning in a marigold-hued, banded wool crepe dress by Narciso Rodriguez—a significant departure from the tweed Michael Kors ensemble she wore to last year's address.

The moment she entered the House of Representatives gallery, the Internet erupted in chatter over the First Lady's sunny dress to track down the designer and where it could be purchased.

The dress, which was reportedly marked down considerably on the Neiman Marcus website, quickly sold out. See more of Michelle Obama's most stunning outfits in our gallery.
