The new “A First Lady’s Debut” gallery at the National Museum of American History in Washington, D.C. includes 11 gowns worn by first ladies from Mamie Eisenhower to Michelle Obama. I got dolled up to cover the public debut of Mrs. Obama’s inaugural gown (and Jimmy Choo shoes!). Michelle’s sparkling ivory chiffon gown is the creation of Taiwanese designer Jason Wu. You can see my report starting around the 1:07 mark.
