Just had a thought about this "It's stupid that the PT decided that Jedi robes should be like Alec Guiness' costume" discussion. When I first saw photos from TPM I never saw anything strange about the Jedi robes looking like this because...
and
and
Jedi were envisioned as Samurai...
...plain and simple.*
Yes Owen's costume is similar:
But I never noticed this as a kid and if you've got an issue with it it's down to the first OT film. This lady isn't a Samurai for example:
The Jedi look was started in ANH, firmly estabablished in ESB and further cemented in ROTJ. The PT got many things wrong but this isn't one of them.
*Oh and BTW the above epic Samurai pic is from Masaki Kobayashi's 1962 film 'Harakiri'. GO BUY IT NOW!!!
