Blue belles of the ball: 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 wore a teal, off-the-shoulder Marchesa gown designed by Georgina Chapman who attended the event
- Samantha Cameron wore an Alessandra Rich dress, on loan to her from the London-based designer, and shoes from British retailer Next
- As Mrs Cameron stepped out of the car Mr Obama remarked, ‘Very pretty,' adding, ‘They look better than us'
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.

'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 grey gown with a sheer overlay, and covered in crystal embroidery.
Mrs. Cameron colour coordinated and wore blue too - her sparkly gown by London-based designer Alessandra Rich featured lace details, a high neck, half sleeves and a belted waist. She had on high black heels from the British retailer Next.
There is great interest in what Mrs. Obama wears to official events because she has been touted as a fashion icon who makes bold choices. On Wednesday, the unexpected piece of her look was the chunky, multistrand silver, turquoise and teal necklace by Tom Binns. Binns also had created the elaborate necklace the first lady wore last year in London when she and the president welcomed the British royals to the American ambassador's home for a black-tie dinner.

'First lady Mrs. Obama always looks so chic and modern. I love the addition of texture with the Tom Binns necklace,' said Roksanda Ilincic, who has dressed both Mrs. Obama and Mrs. Cameron.
Mrs. Obama, in fact, wore a purple dress by Ilincic during that same trip to England.
'Dressing Mrs. Obama and Samantha Cameron have been wonderful. I am honored that each woman representing their countries have been such advocates in their respective roles,' Ilincic said.
The other fashion plate at the dinner was Vogue editor-in-chief Anna Wintour, a well-known supporter of President Barack Obama. She wore Chanel.

If there is one thing the UK state visit to the U.S. has so far proved, it is that first ladies Michelle Obama and Samantha Cameron have both perfected the art of clever capsule dressing, which continued at the dinner with Samantha Cameron pairing her outfit with an Emilia Wickstead belt again.
Earlier, at the special preview for tonight's much-anticipated State Dinner, all it took was a simple removal of a jacket at lunchtime for the First Lady's outfit to be given a whole new feel, exposing her enviably toned bare arms and a brooch for a personal touch.
Speaking at the event, Mrs Obama looked polished and neat - and explained to the visiting school students that while the 'White House is a big place... the kitchen is really teeny... it's a little-bitty kitchen.'
The Zac Posen dress, teamed with a sparkling Kingfisher-esque brooch and navy sash, is part of the suit she wore to this morning's official welcome ceremony and is from the American designer's spring/summer 2012 collection.

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.

By her side, Michelle Obama wore her white Zac Posen suit, teaming its sharp tailoring and clever, pared-down feminine touches with a futuristic and eye-catching pair of silver heels.
The two looked fresh and modern - and sophisticated without being flashy - as they stood out from the backdrop of heavy security and the altogether softer pink magnolia blossom.
They seemed as relaxed and close as ever, laughing in the warmth - though sunglasses would not have gone amiss in the dazzling light.
Mrs Cameron's dress, which retails for around $1,500, is the third item the fashion maven has chosen by the London-based designer in the past four weeks.
Just yesterday, she wore a fuschia top by the label to the mini-Olympics event at DC's American University, again pairing the outfit with an Emilia Wickstead belt.

The two first ladies - known for their individual and confident fashion tastes - stood alongside their husbands on the White House's South Lawn as a 16-gun salute was fired to honour the state visit.
A crowd of 7,000 gathered to watch the formalities as President Obama quipped about the Prime Minister's British peculiarities and revealed that the PM has a basketball hoop at Number 10 Downing Street.
But it is not simply state relations that are close - the President laid a guiding hand on Mrs Cameron's arm at one point and David Cameron was unafraid of receiving a little public affection from his supportive wife as she laid a hand on his derriere.
Indeed, the President made a special mention of Mrs Cameron on her first official state visit.
As dictated by diplomatic traditions, the two couples have swapped presents. The Camerons gave the Obamas a personalised table tennis table and in return received a BBQ grill and personalised chefs whites.

Other gifts included a Jonathan Saunders scarf from Mrs Cameron to the First Lady, reflecting her fashion-driven career and tastes as a flag-bearer for the British Fashion Council, a set of Penguin classics for the Obama girls and White House honey in a crystal honey jar for Mrs Cameron.
Dignitaries including Vice-President Joe Biden and Secretary-of-State Hillary Clinton flanked the podium, where they were joined by Chancellor George Osborne and other senior members of the UK delegation.
As much as the relationship-strengthening trip is about official state business, all eyes are bound to be on the wives tonight at the highly-anticipated black tie state ball.
Chosen gown designers, kept under wraps until the very last moment, can look forward to a flurry of attention following tonight's exposure and the First Lady has in the past been known to propel unknown designers into the mainstream - such as Jason Wu - by wearing just one of their creations.
Yesterday, Mrs Cameron and her American counterpart visited DC's American University where they took part in a mini-Olympics event.

The influential wives came together in a riot of colour - with the First Lady's bright yellow cardigan contrasting vividly with Mrs Cameron's fuschia number.
Saluting American designers, Mobama paired her L'Wren Scott cashmere cardigan with a floral ruffled shirt by the same designer.
A pair of wide-legged white trousers again contrasted with the form-fitting black cigarette trousers sported by SamCam.

Playing tennis in heels and looking as unflappable as ever, Mrs Obama impressed with her willingness to get involved in the activities.
The pair laughed with students and sports players at the event, a nod towards to forthcoming London Olympics Games and to the First Lady's Let's Move campaign.
SamCam paired her pink top and dark belt with the same Joseph cigarette trousers she wore as she landed in the country.

Earlier in the day, Mrs Cameron arrived with her husband David in the U.S. at Baltimore, Maryland Airforce base in a black $935 Burberry trenchcoat from the coveted label's 2012 spring/summer collection.
While a stylish - and ultimately, safe, choice - the coat may have been a questionable move given the unusually warm March day.
