 (CBS) - First lady Michelle Obama wore a stylish spring outfit when she and President Obama met Queen Elizabeth II on Tuesday, but there was once piece of accessory some may think was missing from her look: A hat.

 Dressed in a contrasting turquoise Barbara Tfank dress and pink bolero, Mrs. Obama stood out while standing alongside the Queen, who wore a matching floral dress suit with a light blue hat and Camilla, the Duchess of Cornwall, who donned a cream dress and jacket with a matching hat by Philip Treacy, during the official welcoming ceremony at Buckingham Palace. 
  
  
  
 While headpieces are not by any means required when meeting the Queen, wearing one could be interpreted as a sign of respect to the British monarch. Samantha Cameron, wife of the Bristish prime minister, was severely criticized in the UK for not wearing a hat to the royal wedding last month. 
  
 France's first lady Carla Bruni-Sarkozy wore an understated, grey pillbox hat when she and husband French president Nicolas Sarkoz, arrived for their state visit to Britain back in 2008. 
  
 Hat or no hat, Mrs. Obama's choice outfit was consistent with her personal style: cheerful with bold mix-and-match elements.

  ||||| LONDON – It was all going so well. 
  
  
  
 But when the time came for President Obama to deliver his toast to Queen Elizabeth Tuesday night, the meticulously planned state dinner at Buckingham Palace turned, well, awkward. 
  
  
  
 As Obama began wrapping up his remarks, he put down his notecards and picked up his glass. 
  
  
  
 “Ladies and gentlemen, please stand with me and raise your glasses as I propose a toast,” the president said, as the guests stood up. “To her majesty the Queen.” 
  
  
  
 At this point, the band queued up “God Save the Queen.” But Obama wasn’t quite finished yet. 
  
  
  
 So he kept talking – over the British national anthem – and the president competed with orchestra for a few more seconds. 
  
  
  
 “For the vitality,“ Obama said just before the music started, “of the special relationship between our peoples, and in the words of Shakespeare, ‘To this blessed plot, this Earth, this realm, this England.’” 
  
  
  
 Obama raised his glass, but nobody else in view of the camera followed. And the queen, who had been looking straight ahead, glanced over to offer a pained smile. 
  
  
  
 “A minor mishap,” a BBC commentator said Tuesday night on air. 
  
  
  
 The White House declined a request for comment. ||||| President Barack Obama has made light of a musical mishap that threatened to cut short his toast at Tuesday night's state dinner in London.

 Obama had just toasted the Queen Elizabeth II at Buckingham Palace when the band, apparently deciding that he had finished his speech, struck up "God Save the Queen." 
  
 Obama talked over the music, praising the relationship between Britain and the United States and quoting Shakespeare before the music ended. 
  
 Obama told Deputy Prime Minister Nick Clegg that band effectively gave a soundtrack to his closing passage. Joking about the moment as they met for brief talks Wednesday, Clegg _ who was at the dinner _ told Obama the music had added "a crescendo" to his words. |||||
A:
President Obama just can’t catch a break in London. After screwing up the date in the Westminster Abbey guest book yesterday, Politico reports that he miscued while toasting Queen Elizabeth at last night’s Buckingham Palace state dinner. The orchestra, apparently believing he was finished with his remarks, started playing “God Save the Queen”—right in the middle of Obama’s toast. He kept speaking, right over the British national anthem, and the AP reports that he later joked to the deputy prime minister that the orchestra had simply provided a soundtrack to his words. Michelle Obama had her own minor slip-up: When the Obamas met with the queen earlier in the day, the first lady was sans hat. While hats aren’t required for meetings with the queen, wearing one can be seen as a sign of respect, CBS News reports. And of course in 2009, Michelle actually touched the queen…
