I really, really like this look on Obi-Wan.
Based on:
a 1994 imagining of a prequel-era Obi-Wan
I’m definitely keen on that look, that’s how I feel the Jedi should be. Maybe, his robes in RotS could be all white, the look he has in ANH could just be that he’s been wearing very few different sets of robes - maybe the one set - for two decades in the desert, they’d probably be in a bit of a state
