First lady Melania Trump is donating the gown she wore to President Trump's inauguration ball to the First Ladies Collection at the National Museum of American History.
Melania Trump's donation will join gowns from former first ladies like Michelle Obama, Laura Bush and Hillary Clinton.
The exhibit explores the position of the first lady, which is still an unofficial title. It seeks to examine the ways in which these women have made their own contributions to their husbands' presidential administrations.
When a woman becomes president, she will have to reconsider the duties of the first lady and whether her spouse will be expected to assume the role, the museum says.
First lady Melania Trump added her inaugural gown to a popular Smithsonian exhibit that began more than 100 years ago. Barbara Harrison reports.
