As Barack and Michelle Obama embark on their first official trip to Europe, England is already buzzing about what the stylish First Lady will wear. And if her traveling outfits are any indication, this will be one chic trip across the pond. The First Lady departed the White House in a custom ivory tweed Thakoon coat paired with low Jimmy Choo heels. But like any intrepid traveler, she changed on Air Force One to make her entrance in England in a bold chartreuse Jason Wu sheath under a black coat. Since Michelle is already wearing designs from favorites like Wu (who also designed her Inaugural gown), can we expect to see Narciso Rodriguez and J. Crew pieces on this trip? And what about the traditional hat when meeting the Queen of England? Will she continue to bare her arms? We will have to wait and see — check back for updates throughout the week.
