First Lady Mrs. O spoke at the Department of Health and Human Services today, with a message about healthy living. Read more from the New York Times here. 

For the occasion, Mrs. O turned to a classic skirt and cardigan combination, wearing a black and blue purple print skirt paired with a black cardigan, the latter adorned with a jeweled brooch at the collar. To see a bit more detail on the skirt and pin, click here and here.

Update:  We have confirmed that Mrs.O is wearing Michael Kors violet and black silk ikat brush stroke print skirt. The first lady's black shell and cardigan are Michael Kors as well.

New White House photos on Flickr provide a second look at our favorite dresses of recent weeks.

In the top photo, Mrs. O wears a sequinned Michael Kors frock, worn for the Congressional Hispanic Caucus Institute's 32nd Annual Awards Gala in Washington, D.C.

In the second photo, Mrs. O wears a cobalt blue dress by Jason Wu as she meets former Olympic gymnast Nadia Comaneci. Note the fantastic detail on the crocodile print fabric.

Update #1: We've also added a photo from the gymnastics demonstration that took place on the White House lawn in mid-September. Grazia Fashion has reported that Mrs. O's skirt is Erdem, noting that the designer is "known for his painterly approach to print and colour, and elegant ladylike tailoring." We recall that someone from Mrs-O.org spotted the designer as Erdem a few weeks ago and noted it in the comments. Please remind us who - we'd like to give you recognition!

Update #2: That person is Ari. Hooray!

The president has joined Mrs. O to attend the Chicago 2016 presentation at the Bella Centre in Copenhagen this morning, where the first lady has continued her fashion tour de force. This morning Mrs. O is wearing a lemon meringue brocade matelasse sheath dress, paired with a coordinating cardigan. More to follow.

Update #1: Despite an impressive showing on the part of our first lady, Chicago has lost its bid to host the 2016 Olympics. The AP writes: "Chicago had seemed to pick up momentum in the last few days, with many IOC members seemingly charmed by Mrs. Obama." Count us among those charmed, indeed!

Update #2: Mrs. O is wearing a Michael Kors sunshine metallic silk matelasse sheath dress!
