Right from the get-go, Princess Leia Organa's 'buns' hairdo would be an iconic aspect of the Rebel heroine's character in 1977. The subsequent sequels would also see Carrie Fisher's alter-ego on screen sport a variety of further intriguing hair styles, including a tribute to Nordic female history in The Empire Strikes Back. Sadly, this lovely design idea above, created for Revenge of the Jedi during 1981 pre-production, sadly never made it to the screen. Perhaps this classy, regal look would have been for the aborted Rebels gathering sequence to have been set on the grasslands world of Sicemon?
