Michelle Obama Surprises White House Tour Visitors In DVF Dress (PHOTOS)

Everything Michelle Obama does, she does in style.

The First Lady, with First Dog Bo by her side, wore a Diane von Furstenberg wrap dress to an impromptu meet and greet with White House visitors today, all of whom didn't realize their tourist-y White House visit would end in a tete-a-tete with the First Lady.

The whole thing was broadcast in a streaming video running live on

Mrs. Obama looked casual but stylish in the black and white printed "Julian" dress and some killer patent red pumps as she warmly greeted the visitors and engaged in conversation about The President and her "Let's Move!" campaign.

She even took time to talk style by commenting on one visitor's UGG Boots:

"I've never seen sparkly Uggs before."

The 80-minute long appearance may have been a surprise, but her choice of designer was not. Mrs. Obama has proven to be a longtime fan of the designer and von Furstenberg has been a supporter of the Obamas, most recently contributing to President Obama's Runway To Win collection.

Take a look through the slideshow of our screencaps to see just how great the First Lady looked in DVF (and a few shots of Bo!). (Unfortunately for our purposes, no cameras were allowed for either the tourists OR media.)
