Michelle Obama chose an off-the-shoulder Marchesa gown for her duties as hostess at a White House state dinner honouring the British prime minister and his wife, David and Samantha Cameron.
It was a deep shade of teal in a draped, column silhouette.
The designer of the gown, Georgina Chapman, and her husband, movie mogul Harvey Weinstein, were guests at the affair, but they didn't know Mrs. Obama was wearing one of Chapman's designs when they arrived.
"I'm knocked out!" Weinstein said.
Chapman, not surprisingly, also wore Marchesa, which has made its name on Hollywood red carpets. Hers was a draped blue and gray gown with a sheer overlay, and covered in crystal embroidery.
