Tongues first began to wag when she appeared at President Obama's address to the joint session of Congress in a purple sleeveless dress designed by Narcisco Rodriguez.
Some detractors complained that her attire was inappropriate because it was February, a winter month, and also disrespectful because it was too informal at an official Presidential event where everyone else was wearing sleeves.
But supporters view the first lady's style as modern, confident, and an expression of her chic individuality. She also continues to receive rave reviews from the fashion world on her bold choices of attire.
Most recently, Michelle Obama fanned the flames of controversy by posting her first official White House photo on her website
. In the photograph her arms are bared in a perfectly fitted, black crepe-jersey racerback Michael Kors gown accentuated with elegant white pearls.
She will also appear on the March cover of Vogue wearing a — you guessed it — sleeveless magenta silk dress by designer Jason Wu.
The only other First Lady to be photographed sleeveless for their official White House photo was Mamie Eisenhower
