Morgan chose not to depict the wedding of Charles and Diana itself, focusing instead on the couple's engagement period; according to Corrin and O'Connor, this was because the ceremony can easily be viewed on YouTube. Nevertheless, Diana's wedding dress was recreated for the episode's final moments. Costume designers Amy Roberts and Sidonie Roberts consulted with the real dress's designers, David and Elizabeth Emanuel, to recreate the item; according to Caron, seeing Corrin wearing the dress rendered the production crew speechless. Elizabeth Emanuel expressed her approval of the dress's recreation.
