After going through a week's worth of outfits in two days, "Mighty Michelle," as the British are calling her, has left the U.K. for France.
The meeting of world's most fashionable first ladies was perhaps the most widely anticipated photo-op of the Obamas' European tour.
Daily Beast editor Tina Brown speculated that it would be "the most delicious, sartorial fashion moment that we are all going to be deconstructing for next two or three weeks."
Dressed in a black-and-pink patterned floral dress coat, Mrs. Obama greeted her French counterpart by saying, "Bonjour." Mrs. Sarkozy wore a gray silk-belted dress.
The looks were remarkably similar, with large bows at the neckline, falling just below the knee. Under her coat, Mrs. Obama wore a short-sleeved bright pink dress of a similar pattern. The first lady opted for kitten heels. Mrs. Sarkozy wore flats.
The couples lunched together, dining on guinea fowl stuffed with foie gras, coquilles Saint Jacques and asparagus.
The Obamas traveled to France for the 60th anniversary of the North Atlantic Treaty Organization. To mark the occasion, Germany and France are co-hosting a summit for member countries.
But even before the summit, from the moment the Obamas stepped off Air Force One outside London Monday night, so many eyes have been on first lady Michelle Obama.
This is the first time in nearly 50 years, since Jacqueline Kennedy took a trip across the pond, that Europe has so widely anticipated a visit by a U.S. first lady.
The trip may be her husband's debut on the world stage but it is the first lady who just might steal the show. In much of the British tabloid press, it is Michelle Obama, not her husband, who is the main focus of the "Obamamania" headlines.
Mrs. Obama's visit to an all-girls school in London Thursday seemed more like an appearance by English soccer star David Beckham or pop boy band The Jonas Brothers, with shrieking students clamoring to get close enough to greet her.
The European reaction to the Obamas recalls the Kennedy's trip to Paris in 1961, when Jacqueline Kennedy wowed with her glamorous style and fluent French.
The attention and reception the first lady received on that trip prompted the president to joke about his standing in the power couple. "I am the man who accompanies Jacqueline Kennedy to Paris," Kennedy said.
Much like Parisians' reaction to Jackie Kennedy, so too are the Brits "completely in love" with Michelle Obama, said Alexandra Schulman, editor of London Vogue.
"She's something different," Schulman said. "She looks like she's enjoying herself. She's glamorous, she has a fresh glamour. We love it if it's another country's political wives looking glamorous. We have more problems and are more critical when it's our own and our politicians' budgets that are being spent on their dress, sadly."
Much of the attention on the first lady has focused on her wardrobe.
The Obamas drew a large crowd of spectators outside Buckingham Palace Thursday, and talk of the first lady's attire dominated the conversation.
"She's very stylish, always looking amazing, always looking very smart," Rachel Abbott said.
Her friend Katie Hunt agreed. "She's probably in the Top 10 of being best dressed, in the world."
