At the Smithsonian's American Portrait Gala in 2019, Obama wore a Schiaparelli haute couture gown, which had a bust neckline.
"The inspiration for the shape originally came from the crinoline, which is often found underneath couture gowns, but the real starting point for the overall look was the color," Schiaparelli's creative director, Daniel Roseberry, said in a statement in 2019. "The acidic tone echoes Elsa Schiaparelli's signature shocking pink, and we also felt that it matched the strength and energy of Mrs. Obama. It was such an honor to make this special gown for her."
