Samantha Cameron and Michelle Obama kept up their reputations as the first ladies of fashion in floor length blue gowns for a star studded state dinner in Washington.



David Cameron, the Prime Minister and his wife were the guests of honour at the biggest party ever hosted by President Obama and his wife Michelle.
As well as a contingent of senior British and American politicians, there was also a number of musicians, sportsmen and entertainers among the 360 guests, bringing a touch of the red carpet to the White House's South Lawn.
Actor George Clooney was one of the surprise guests and despite sitting near Mrs Obama at the head of the table, he reportedly spent much of the evening talking to Valerie Jarrett, one of the President's senior advisers.



The fashion stakes were similarly high with Mrs Cameron continuing to support home-grown talent. The Prime Minister's wife wore a blue patterned Alessandra Rich dress, which was on loan from the British-based designer, along with shoes from Next.
