First lady Michelle Obama, who has been called a new fashion icon, will grace the cover of Vogue’s March issue.“'I love clothes,'” she tells the magazine.“'First and foremost, I wear what I love. That’s what women have to focus on: what makes them happy and what makes them feel comfortable and beautiful. If I can have any impact, I want women to feel good about themselves and have fun with fashion.'”But the new first lady is also pragmatic and is willing to take some fashion criticism here and there. “'I’m not going to pretend that I don’t care about it,'” Mrs. Obama says of negative reviews of the outfit she wore in Grant Park on Election Night.“'But I also have to be practical. In the end, someone will always not like what you wear – people just have different tastes. Some will think that sweater was horrible, [but] I was cold; I needed that sweater!'”
