Michelle Obama is a practical dresser

London: US first Lady Michelle Obama known for her stylish taste in fashion says she is a practical dresser. According to her the decisions on what she wears are based on what she`s doing that day because she needs to know she`s in the right outfit, reports a website. "It`s really just sort of, how cold is it? Do I have to stand outside, and what am I going to use to cover my arms if I`m freezing so I`m not shivering while I have to give a speech? It`s really stuff like that. And I know people are sort of thinking that it`s different, but it`s real practical stuff like that," said Michelle. In December, Michelle stunned the fashion world by wearing a vintage dress to a high profile public event. The mother-of-two wore a black lace outfit by the late designer Norman Norell to the Christmas in Washington concert and it is thought she was the only first lady in history to ever wear a second hand gown for an official engagement.
