Also people tend to forget that Luke's black outfit in ROTJ was supposed to represent his brush with the dark side. Of course him actually tuning evil was eventually written out, but Luke did have his dark side moment while fighting Vader in the end.
As far as the lore is concerned I can't remember having ever read that it was supposed to be an actual Jedi outfit. I'm pretty sure it was just something he put together before meeting Jabba (even the pre-PT EU added a practical explanation for the outfit.)
And of course when we see Anakin (Sebastian Shaw) at the end of ROTJ he's wearing the same moisture farmer outfit that Obi-Wan wore in ANH. Not to mention that Yoda more or less wears the same outfit. I don't actually now if this is a pre- or post-PT thing, but the reasoning behind the Jedi both in the OT and PT wearing moisture farmer outfits, or rather just a casual outfit common among colonists and farmers, were because they were supposed to be ascetics; monks more or less. Hence the humble outfits.
And Lucas was quite adamant back in the pre-PT days that the Jedi order was basically just warrior Buddhist monks, even comparing them to Yogis once.
I certainly took Luke's ROTJ outfit as a "Jedi uniform," and, given the context of the film, it seems we were were meant to. Yes, he resembles Vader, and there is thematic significance to that. But I always saw the primary, in-universe reason for that similarity being the simple fact that Vader was once a Jedi too; thus he continued to dress more or less like a Jedi, and continued to carry and use what Palpy disparagingly referred to as "a Jedi's weapon." I mean, why else would Luke make his first public appearance as a Jedi (that's how he introduced himself to Jabba) dressed in such a strikingly distinctive uniform? The fact that the outfit strongly resembles a priest's cassock also cemented the idea (in my mind at least) that this was indeed a "Jedi uniform." to boil it all down to "he wore black because he was turning toward the Dark Side" strikes me as overly simplistic, and pretty nonsensical from an in-universe standpoint (Luke: "I'm seriously thinking of turning to the Dark Side, so I'd better get myself some pretty funereal duds ASAP...").
As to Anakin's ghost wearing Tatooinian robes - well, Anakin was a Tatooinian. So, there's that.
Yoda's garb was fairly different from Anakin / Obi-Wan's - much more generic hobo / hermit clothing - very rudimentary. Also, I'm of the opinion that Yoda - being a Jedi master (not a Jedi Knight) - would not have worn the militaristic uniform of a Jedi Knight, nor would he have ever carried a lightsaber. That was also Lucas' opinion back in the OT days, as evidenced by the Rinzler books.
