It occurs to me that Obi-Wan Kenobi’s first name (added in the 1976 draft) suggests a “pale belt” or a white belt from karate (suitable for a wizardly advisory figure, in the vein of Gandalf the White).
Then I remembered that Edgar Allan Poe allegedly contrived to get himself thrown out of West Point by wearing “white belts and gloves, under arms” during a parade inspection, as per regulations… but nothing else.
Then I remembered that around the time of the 1975 third draft, Lucas drew on Kurosawa’s Hidden Fortress for inspiration by consdiering casting Ben Kenobi as Japanese, and Leia as either Japanese or part-Asian, suggesting a familial relationship of some sort.
And then it came to mind that Ben Kenobi had a prosthetic left arm in that draft also.
And then I thought about how people in the desert climate of Edgar Rice Burroughs’ Barsoom generally don’t wear clothing except for the leather straps of their “war harness”.
Now I’ve got a vision in my head of Leia Organa, Queen of the New Alderaan colony on Tatooine, going around wearing nothing but some strategically placed belts and long gloves to cover up a pair of droid arms.
I think I might have done a little too much LDS, as they say. 😉
