sleeveless for US First Lady

Critics have noticed the fashionable way that the US First Lady Michelle Obama is seen showing off her arms in her finely donned clothes.  It seems like a lot of people still can't accept this kind of style worn by top officials or first ladies of any country.  But considering the First Lady's overall physical fitness, I think she is able to do justice to her clothes, with or without sleeves.  Former 1st Lady Jackie O did it in her most glamorous style, and we don't see why M. Obama shouldn't be allowed to express her true style.
