Well, he would wear black tie to the theatre and ballet, and white tie to the opera. As Highland dress is only worn in Scotland, he would wear a dinner jacket to the theatre and ballet, and full dress (white tie, tail coat etc) to the opera. If Prince Charles were to attend these events in Scotland he might wear Highland evening dress such has been shown.
