The First Lady has arrived in London! Mrs. O began the day with a visit to the US Olympic team in east London, wearing a red peplum top paired with a red and white print jacket. From there, Mrs. O moved on to the American Ambassador's Residence, Winfield House, where she hosted 'Let's Move London' joined by David Beckham. For the second appearance, Mrs. O sported white pants paired with a two tone blue athletic top, piped blazer and sneakers.
Update #1: Thanks to reader "lisa" who notes similarity between Mrs. O's red top and the Zara double cloth top, available here in black and white. Thanks to reader "CarolAnn" who has spotted Mrs. O's red and white print blazer as the Thakoon Chevron Print Blazer, available here. Thanks to reader "MDavis" who has spotted Mrs. O's light blue blazer as the Talbots Grace Fit Piped Seersucker Jacket, available here.
Update #2: Adding an "Official White House Photo" from the Let's Move London event. The First Lady wears a great striped top, which reader "Dana" identifies as the Colorblock crewneck sweater from the Gap, available here.
