The media has had a field day with the new First Lady’s wardrobe choices lately. She has appeared bare-armed on three separate occasions this week. First in an emerald, tea-length dress she wore to present the Library of Congress Gershwin Prize to Stevie Wonder.Then again on the cover of People Magazine in a sleeveless magenta Tracy Reese frock. Then on Tuesday night, it happened, perhaps the most controversial showing of her biceps at the President’s first congressional address. She wore a plum Narciso Rodriguez dress…sans sleeves and ignited the fury that has been deemed, Lady Obama’s right to bear arms.

“While her sleeveless dress trend is definitely a talking point, she’s always very conservative in other ways. The dresses are often cut below the knee, and it’s not a deep, plunging neckline,” says Glamour.com’s senior fashion editor, Susan Cernek. “She’s balancing out the expanse of skin on her arms by not showing too much elsewhere. That’s what makes her look very appropriate.”

While our new first lady has been hailed as the most fashionable first lady since Jackie O, some think she is taking her fashion sense too far. Going sleeveless in Congress, during WInter, is next to tawdriness according to some Chicago Tribune readers.

“Does the lady not understand that these Big Speech Events are serious and important? Not a cocktail party?” e-mailed one Tribune reader, who said she scanned the crowd for other bare arms and spied none. “The season is winter. The occasion is business. Dress was wrong place and time.”
