The first lady wore a splendid pink Isabel Toledo ensemble, embellished with a stunning Erickson Beamon pin at the shoulder, to host a White House luncheon for recipients of the National Design Awards. Among those to be honored by the Smithsonian's Cooper Hewitt, National Design Museum, are sister-design duo (and Mrs. O favorite) Rodarte. Per the AP, the first lady called the winners "some of our country's most talented, most visionary, most public-minded designers."

In her own subtle way, it seemed perhaps Mrs. O was honoring design talents Isabel Toledo and Erickson Beamon too! On hand to see the ensemble, the AP describes it as, "a V-neck top, drapes of fabric at the waist and loose flowing pants."

One tidbit to share, pointed out by "Meredith P":  Upon learning that she would be seated next to Tim Gunn, the first lady said, "How cool!" And it seems the feeling are mutual. Tim Gunn later took to Facebook, writing:

"Hi everyone! I just had to get on Facebook and share the incredible day I had with you. I had the absolute honor and privilege of being seated next to Michelle Obama today at a lunch held to honor National Design Award winners at the White House. She is so stunning! I literally could spend each afternoon with her - it was such a pleasure!"

There is a good deal of similarity between this pink ensemble and the black Isabel Toledo tunic and pants that Mrs. O wore to a Vogue/Calvin Klein fundraiser in 2008, seen here. Also to mention, NY Mag reports that the Mulleavy sisters of Rodarte were unfortuantely unable to attend the White House luncheon.

First Lady Mrs. O spoke to dance students from the Duke Ellington School of the Arts and the Joy of Motion Dance Center, as they rehearsed a segment from the Broadway show 'Hairspray' at the White House today. For the event, the first lady wore a pale green, lightweight pant suit, paired with an Erickson Beamon techno deco belt.

Update: Mrs. O's matte jersey pant suit is designed by Stephen Burrows. And the official word on the much-debated color? Sunrise Yellow.

The much anticipated state dinner festivities have begun! The president and first lady welcomed Mexican President Felipe Calderon and First Lady Margarita Zavala to the White House with an outdoor arrival ceremony earlier today.

First Lady Mrs. O dressed in a classic raspberry coat and dress (confirming designer), paired with a statement bib necklace and black pewter heels. The turquoise and orange flecks of color in the necklace certainly pop against the pink dress - gorgeous!

The first ladies later visited New Hampshire Elementary School in Silver Spring, Maryland, which was awarded the USDA's Healthier US School Challenge Silver Award in 2009. Note Mrs. O's change to orange-gold flats!

The first lady attended the National Science Bowl in Washington, D.C. today, where she posed the final round of questions to contestants. While there, Mrs. O announced that the White House would host a Science Fair for students from around the country. The New York Times has the full scoop, here.

Style wise, the first lady turned to a minimalist grey pant suit, paired with silver ballet flats and an oversize pin at the shoulder.

Update #1: Mrs. O's light grey silk/wool suit is a Narciso Rodriguez creation. No word quite yet on the absolutely splendid brooch.

Update #2: Mrs. O's brooch is an Erickson Beamon creation. Fabulous!

Tuesday marks the official launch of the First Lady's campaign against childhood obesity, and it seems Mrs. O media appearances will abound.

Per Lynn Sweet of Daily Flotus:

Mrs. Obama's East Wing said she will be "joined by members of the president's cabinet, as well as media, sports, entertainment, and business leaders," plus mayors, member of the medical community and others at the White House event. On Tuesday evening, Mrs. Obama will sit down with CNN's Larry King for an interview about obesity and her first year as first lady. She will take questions from viewers.

Additionally, Mrs. O will appear on Good Morning America, a first peek of which we have here:

On a style note, the first lady is wearing an ivory double face wool sheath dress and jacket from Talbots for her interview with Robin Roberts. Mrs. O first wore the dress in November for a White House classical music event, seen here. Completing the ensemble is a pair of knee high boots in camel.

Update #1: Mrs. O's Super Tuesday is off and running! This morning the president signed a memorandum as part of Mrs. O's campaign to combat childhood obesity. The president and first lady were joined by Education Secretary Arne Duncan, Health and Human Services Secretary Kathleen Sebelius, Agriculture Secretary Tom Vilsack, and Interior Secretary Ken Salazar in the Oval Office of the White House.

For the signing, Mrs. O wore a teal dress with printed top, paired wtih a coordinating teal cardigan. A statement brooch by Erickson Beamon completed look. See photo above.

Update #2: The first lady has just unveiled a new website for her campaign against childhood obesity, Let's Move. In the email introducing the website, Mrs. O writes:

"The problem is clear. Over the past three decades, childhood obesity rates in this country have tripled. Today, obesity and excess weight threaten the health of one out of three American children. It’s time for us to act. That's why I’m asking you to be part of Let's Move! -- a nationwide effort to solve the obesity epidemic within one generation."

The site also includes this video from Mrs. O (wearing a J.Crew cardigan for the seated interview):
