Earlier in the day, the first family served lunch at So Others Might Eat in Washington. The soup kitchen opened in the 1970s and now serves more than 1,000 men, women and children each day. Mrs. O kept her look casual, sporting cropped pants, a blue cardigan and her purple Converse as she served lunch.

Today marks the 46th birthday of First Lady Mrs. O. Mrs. O has been treated with a few celebrations over the past few days, first with White House staffers on Friday, and last evening, with the president and a group of Chicago friends. Last evening the group spent more than four hours at Nora in Washington, D.C.. Lynn Sweet has the full scoop, here. Mrs. O chose a black dress for the fete, topped by a black coat embellished with gold lattice detailing.

Update: A gold star for reader Kathryn, who reports that Mrs. O's coat is Narciso Rodriguez, as seen here.

Below, White House staff closed the week by honoring the First Lady's birthday on Friday. The first lady wore a watercolor print, ruffled blouse for the occasion.
