Zegler was on hand with Snow White director Marc Webb to perform the song “Waiting on a Wish” one of the original songs created for the Snow White remake. The song was performed in front of The Alcázar of Segovia, a castle in Segovia which was the inspiration for the castle used in the original 1939 movie, Snow White and the Seven Dwarfs.

For the occasion, the “West Side Story” breakout star channeled Disney princess whimsy with a dash of opulence for her promotional event, wearing a custom Elie Saab haute couture look. The white gown featured a bevy of feminine elements.

Rachel Zegler channeled her inner princess in a romantic ballgown. Zegler, 23, looked as elegant as ever in a white Elie Saab gown at a Snow White photocall in Segovia, Spain, on Wednesday, March 12.
