Mrs. O arrived this morning in Copenhagen for the IOC's Olympic bid meeting. A true advocate to her home town, she will spend the next two days rallying in support of Chicago as the home for the 2016 Olympics. Stepping off the plane, Mrs. O wore a bold, geometrically patterned jacket paired with a knee-length black and white tweed sheath dress. A trademark bow belt added a final detail at the waist.
It may have been a black and white ensemble, but we give it a gold!
Update: Mrs. O wears a Jason Wu tweed dress, paired with a Zero + Maria Cornejo Ivy jacket in printed tweed with a grosgrain belt.

Mrs. O is on the cover of the November issue of Prevention Magazine, wearing a fantastic beaded Jason Wu cocktail dress and Jimmy Choo Lantern heels. The dress hails from Jason Wu's Fall 2009 collection, seen here.
We have to say, this may be one of the best Mrs. O covers ever! We love the natural outdoor setting, and Mrs. O looks beyond fabulous. To read more about the interview, click here.

The President and First Lady Mrs. O are back from the Pittsburgh Summit, attending the Congressional Black Caucus Foundation's Annual Phoenix Awards Dinner in Washington, DC last evening. Mrs. O debuted a new black cocktail dress for the occasion.
Update: As several people suggested in the comments, we've confirmed that the First Lady's dress is in fact a Jason Wu design. Fabulous!
