Michelle Obama bares arms in official White House portrait

20090227mrsobamaportrait First Lady Michelle Obama is wearing a sleeveless black shift dress by Michael Kors in her official portrait, released by the White House today.

Her choice of a sleeveless dress makes the arm-baring style her official signature. Expect her to keep baring her muscular toned arms for the next four years.

Better get used to it, folks.

Michelle wore sleeveless on the recent covers of People and Vogue. And she chose a controversial Narcisco Rodriguez sleeveless black V-neck blouse for her husband's first address before the Congress earlier this week.

But this is the first time Mrs. Obama has worn a dress by Kors, one of the most well-known American designers, thanks to his judge role on the popular reality fashion show, "Project Runway."

Who's next, Christian "Hot Mess" Siriano?

What do you think of the First Lady's choice? We have to admit we love it.

She looks classic, elegant, down-to-earth and appropriate.

And the pearls are perfect. She's totally flawless and completely American.
