Michelle Obama is the first lady of America. She visited China on March 20th, 2014. When she met the president Xi, she wore a red dress. She said her red dress is always ready for the important moment. Do you know she is also the first lady of fashion American?
    Every first lady since Lou Hoover (except Bess Truman) has appeared in the high-fashion magazine, Vogue. But Mrs. Obama is only the second to appear on the cover. She appeared wearing a pink silk dress by Jason Wu. When she was interviewed by the editor of Vogue, Mrs. Obama said what she wears is always paid attention to by many people. “I'm not going to pretend that I don't care about it.” she said. Most cover models have their clothes chosen for them by Vogue, or at least editors work as advisers. However, Mrs. Obama did choose outfits for the Vogue photos from labels(商标) she had worn before. “She doesn't need any help. She loves fashion and knows what works for her,” Talley said. “She's never had a conversation with me about, `What do you think?' or `How did this look?' And I'm glad for that.”
