President Donald Trump and first lady Melania Trump take the stage at the Inaugural Ball in January 2017. Melania Trump wore a sleek, off-the-shoulder gown with a cascading ruffle and thigh-high slit. The design, which was a collaboration between Mrs. Trump and designer Herve Pierre, a former creative director for Carolina Herrera, featured a small, knotted belt at the waist.
