The First Lady celebrated Independence Day wearing a Boy. by Band of Outsiders Degrade Toile de Joie Dress, previously seen here in June 2012. Red flats completed the look.

The President and First Lady traveled to Chicago for the weekend to attend the wedding of Tony Balkissoon and Laura Jarrett (daughter of Valerie Jarrett, senior advisor to the President). From Chicago, the First Lady will head west to give a commencement address at Orgeon State University, before campaigning in Nevada and Colorado. (The President heads south to Los Cabos, Mexico for the G20 Summit.) For weekend travel, Mrs. O paired a black and white floral skirt with a black tank and signature Alaia belt. Lovely!
Update: Mrs. O wears a black and white toile de joie skirt by Boy. by Band of Outsiders (a new First Lady favorite?) available in a shorter version here.

It's been a full day for the First Lady. This morning, wearing a Preen pixel print dress paired with a honeydew hued jacket, Mrs. O joined Walt Disney Company Chairman and CEO Robert A. Iger to announce that Disney will introduce new standards for food advertising on programming targeting kids and families.
Next up was an interview with the Associated Press to promote the publication of the First Lady's new book, American Grown. For the occasion, Mrs. O wore an ombre blue floral shirt dress paired with a belt and cardigan. Very "ladylike with a twist" on both occasions!
