Michelle Obama in Vintage - What’s old is new again for Michelle Obama, who had another groundbreaking moment in fashion history Sunday night, dazzling in one-of-a-kind vintage number by the late designer Norman Norell. The First Lady picked up the black-lace overlay dress, which boasted a full tea-length tulle style skirt and a square neckline (something rarely seen in contemporary designs), at New York Vintage boutique, signaling what store owner Jon Schneck believes to be the first time a first lady has worn a vintage dress to a public event, reports The Huffington Post. Obama donned the elegant 1950s piece to the “Christmas in Washington” concert in Washington, D.C., which airs tonight on TNT and is hosted by Ellen DeGeneres. And while the spectacle, which will feature performances by Mariah Carey, Annie Lennox and more, will surely be packed with flare, we’re sure no one sparkled as brightly as Obama, who glammed up her ballerina-like confection with oversized snowflake drop earrings.
