The 50th anniversary ceremony today for the March on Washington featured plenty of moving, stirring moments, but in case you were wondering, that was a Tracy Reese frock Michelle Obama was rocking.

The first lady, as usual, stood out, even with the likes of Oprah Winfrey and Caroline Kennedy on the steps of the Lincoln Memorial, attired in a black flared sleeveless dress ($498) splashed with huge red flowers by one of her favorite designers.

She especially stood out when she appeared just below the statue of a seated Lincoln with three presidents — President Obama, former president Bill Clinton and former president Jimmy Carter — to wave at the crowd gathered to commemorate the 1963 nation-changing March on Washington and the Martin Luther King Jr's "I Have a Dream" speech.

Reese, for one, was thrilled. "We are honored that the first lady would choose to wear one of our designs during the celebration of such a deeply significant historical moment. Mrs. Obama's radiance makes our dresses shine!" Reese said in a statement.

Mrs. O's hair — newly highlighted in subtle coppery-gold tones, as People was first to note — was pulled up and back off her face in the muggy, overcast miasma of a Washington late-August day.

Oprah was dressed simply in a white blouse and black pencil skirt, while Kennedy sported a dark blue sheath with a white batik-like print. Also among the group on the steps was Lynda Bird Johnson Robb, daughter of the late President Lyndon Johnson, who was vice-president at the time of the march (President Kennedy would be assassinated a few months later). Once he became president, Johnson was a driving force in the passage of crucial civil-rights legislation in the following year.
