Michelle Obama is the first lady of American fashion, appearing on the cover of the March issue of Vogue.

Every first lady since Lou Hoover—except Bess Truman—has been appeared in the high-fashion magazine, but Mrs. Obama is only the second to appear on the cover. She appears wearing a silk dress by Jason Wu.

Vogue’s editor Andre Leon Tally recalled his interviews with Mrs. Obama ahead of US president Barack Obama’s swearing-in ceremony（就职典礼）. “One of the best experiences of my life .” “She is so easily reached, natural and normal.” he said.

Mrs. Obama described her role as “Mom in chief” to 10-year-old Malia and 7-year-old Sasha. “I’m going to try to take them to school every morning, as much as I can,” she said. “But there’s also a measure of freedom. And clearly there will be time I won’t be able to drop them off at all. I like to appear in my kids’ school. I want to know the teachers; I want to know the other parents.”

Being in Vogue, though, the chat finally turns to clothes. “I’m not going to pretend that I don’t care about it,” she said. “But I also have to be very practical. Someone will always not like what you wear---people just have different tastes. ”

Most cover models have their clothes chosen for them by Vogue, or at least editors work as advisers. Not this time. “She doesn’t need any help. She loves fashion and knows what works for her,” Talley said. “She has never had a talk with me about, ‘What do you think?’ or ‘How does this like?’ And I’m glad for that.”
