She turned heads in a pale pink, off-the-shoulder dress by Carolina Herrera.
Pretty in pink!
Her outfit echoed a dress once worn by the late Princess Diana, who wore a Catherine Walker ballgown with a similar neckline and light pink hue during a visit to the Berlin Opera House in 1987.
Princess Diana wore the striking gown to a gala in 1987.
Both dresses had pink buttons down the bodice, although Diana’s buttons were smaller and seemed more decorative than functional.

It’s unknown whether the duchess's dress was directly inspired by Diana’s ‘80s look, but the royals do have a history of wearing items that echo the late princess’s most memorable style moments.
