Samantha Cameron and Michelle Obama fly the flag for home designers as they colour co-ordinate their gowns at the White House state dinner

Michelle Obama chose an off-the-shoulder Marchesa gown for her duties on Wednesday night as hostess at a White House state dinner honoring the British prime minister David Cameron and his wife Samantha.

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 did not know Mrs. Obama was wearing one of Chapman's designs when they arrived.

The First Lady, 48, described the planning that goes into the official dinner and treated the American and British students to a rare glimpse of the White House's behind-the-scenes goings-on.

In the meantime, the British Prime Minister's wife, 40, had stayed in the same Roksanda Ilinic dress, looking demure as ever in the aqua-sleeved, navy blue and white number which neatly translated from the formality of the morning's welcome ceremony to a luncheon at the State Department.

She had paired the dress with the same belt she wore yesterday and again wore the classic pumps that she has sported throughout her trip so far.

This morning delivered a dose of unseasonably warm sunshine - and fine fashion choices - to the capital.

SamCam took full advantage of the balmy weather, wearing the cleanly-cut, bold shift dress and no jacket to the UK state visit's official welcoming ceremony.
