In the blue corner … it's a fashion face off on Downing Street as Samantha Cameron makes a royal fashion faux pas by wearing the same cornflower colour as the Queen
16:39 GMT, 24 July 2012
As a member of the British Fashion Council Samantha Cameron rarely puts a well-clad foot wrong when it comes to matters of style.
But today David Cameron's wife made a rather public fashion faux pas by choosing the same light blue colour palette as Queen Elizabeth to welcome her Majesty to Downing Street.
As their husbands Prime Minister David Cameron and Prince Philip stood awkwardly by their side the two women posed together in the sunshine, and while Samantha smiled happily for the photographers the Queen's stony face told a very different story and it was clear that the monarch was not amused.
Blue is the colour: Samantha and David Cameron were hosting lunch at Downing Street for the Queen as part of the Jubilee celebrations where both Samantha Cameron and Queen Elizabeth II chose blue patterned outfits

Feeling blue: Clarence House have confirmed that there are 'no rules' when it comes to choosing an outfit to meet her Majesty, but Queen Elizabeth II looks unimpressed by Samantha Cameron's wardrobe today
A spokesman from Clarence House confirmed today that there are no rules when it comes to choosing an outfit when meeting the Queen, and the Royal never makes the colour of her clothing known before an event.
But the wardrobe clash will be an embarrassment for the brunette who is known for her immaculate styling.
As well as being startlingly similar in colour both outfits featured a digital style blue and white print.
Samantha finished her Jonathon Saunders shift dress with a nude belt and high street heels from LK Bennett while the Queen chose her signature black patent block-heels and matching bag to accessorize her midi-skirt and round-necked jacket.
Queen Elizabeth and her husband the Duke of Edinburgh were visiting Downing Street for a lunch
being held as part of the Queen's Diamond Jubilee celebrations marking her 60 years on the throne.
Past prime ministers Gordon Brown, Tony Blair and John Major were also guests of honour (not wearing powder blue).

THRIFTY SAMCAM FLIES THE FLAG FOR BRITISH FASHION
Jonathon Saunders Blue Serle dress was 825 now 495 at Matches
The Queen might not be amused by Samantha Cameron's outfit choice but the designer dress and high street shoes she chose for the event are a brilliant nod to British fashion as the UK counts down to the London Olympics.
As an ambassador for the British Fashion Council Samantha is a huge champion of British designers and Jonathon Saunders, the Scottish label behind the blue digital print dress she chose today is one of her go-to designers for prestigious events.
Samantha even gifted Michelle Obama a scarf from the label's Spring/Summer collection during a visit to the UK earlier this year.
And our thrifty first lady showed off her eye for a bargain: the blue 'Serle' dress is now in the sale for 495 (40% of it's original 825 price tag).
The stylish brunette teamed the knee-length dress with 195 classic suede courts from Kate Middleton's favourite shoe brand L K Bennett.
DEJA BLUE: IT'S NOT THE FIRST TIME THIS HAS HAPPENED
As the most photographed woman in the world with a diary packed with social engagements it isn't a surprise that the Queen sometimes finds herself in a matchy matchy outfit situation.
But if the Royal rumour mill is to be believed Her Majesty won't even notice.
According to Windsor spies Margarat Thatcher once suffered a withering wardrobe put-down at the hands of Elizabeth II, or rather her office.
Having splashed out on a bespoke electric blue dress for one of her first meetings with the Queen after being elected as Prime Minister Thatcher was mortified to arrive and realise she was wearing almost a carbon copy of the Queen's outfit.
The next day she sent a hand-written letter to the Palace apologising and suggesting the two women colour co-ordinate in the future to avoid embarrassment.
The reply from Palace aides was swift, and cutting, reading simply: 'The Queen does not notice what anyone else is wearing.'
