The First Lady appeared at Children's National Medical Center this afternoon to read "The Night Before Christmas," as has become annual tradition. With Santa by her side, Mrs. O was dressed in a Marc Jacobs print dress, previously seen here. A gold bow pin at the neckline completed the look.

A gusty day in Dublin gives us a better view of Mrs. O's dress! The First Lady wears a Silk Circle Jacquard Dress by Marc Jacobs in a marigold and berry retro geometric print. The dress hails from the designer's Spring 2011 collection.
After a trip to the village of Moneygall, the President and First Lady were back in Dublin to address a crowd at Trinity College.

The President and First Lady enjoyed a pint of Guinness at Ollie Hayes pub in Moneygall, Ireland this afternoon. The visit involves a bit of family heritage: President Obama's great great great-grandfather, Falmouth Kearney, hailed from the village of Moneygall in County Offaly, Ireland.
For the second appearance, Mrs. O wore a geometric print dress paired with an easy-fitting sandstone trench. Easy and chic!
Unfortunately, it looks as though the President and First Lady's trip to Ireland will be cut short. Originally scheduled to spend the night, the AP reports that the couple will fly to London this evening as ash from an Icelandic volcano moves toward Europe.

It's back to work after a glam-filled evening for Mrs.O. Walmart President and CEO Bill Simon announced today that Wal-Mart would make a comprehensive effort to provide healthier and more affordable food choices to customers. The First Lady was on hand to support the effort, declaring, "It's a victory for parents. It's a victory for families, but most of all, it's a victory for our children." Walmart has said that the First Lady's "Let's Move" initiative was catalyst for the new commitment.
For the speaking affair, Mrs. O wore a grey tweed, collared sheath dress, paired with knee-high brown suede boots. A new wavy hairstyle completed the look.

In October 2009, Glamour's Tracey Lomrantz asked The Washington Post's Robin Givhan what designer she would like to see added to Mrs. O's sartorial repertoire. Robin Givhan's response?
"I think it would be interesting to see her in Marc Jacobs. And I say that because he's probably one of the most directional American designers, so it would be interesting to see if she could incorporate pieces from his collection into her wardrobe and make it something that could work in the White House."
Just as Robin Givhan's set to leave for The Daily Beast, she has her wish! Pictured above with an a capella group that performed at the White House on December 10, Mrs. O wears a dress from Marc Jacobs Fall 2010, seen on the runway here. Thank to reader "marky mark" for the tip, which has been confirmed. For a close-up of the dress on the first lady, click here.
