This is why Larlarb opted for Obi-Wan’s blue attire — not just because it makes sense as something he would actually wear to blend in more with the locals on Tatooine, but also because it’s symbolic of where he is mentally and emotionally when the series begins. Larlarb explained:
“With the blue, we can understand that he is not the same Jedi legend. As a Tatooine citizen, he has a more relaxed, less structured feel than the Jedi elite. We could play on the shapes of the garments to the degree where I was making choices that were less architectural than the Jedi [clothing] language. This fits into the Tatooine language, and this is the main factor. He’s hiding in plain sight among Tatooine’s population.”
In time, Obi-Wan makes peace with the demons of his past, but it’s obviously a gradual process that takes place over the course of the series. This, too, is reflected in the ways his clothes evolve throughout the show. While Obi-Wan begins to dress the part of the Jedi he once was upon undertaking a mission to protect a young Leia (Vivian Lyra Blair), “the precision of his Jedi look doesn’t come until later in the series,” Larlarb observed. “We build our Obi-Wan back piece-by-piece until the inarguable Jedi has returned.”
Costuming has always been an extremely important component of the visual storytelling language of “Star Wars” (what would Vader even be without his jet-black life support system?), and Obi-Wan’s getup in the “Obi-Wan Kenobi” series is no exception. That his blue outfit also nicely compliments McGregor’s naturally blue eyes, well, that’s just the icing on the cake when it comes to really nailing that “Sad Jedi Boi, But Make It Fashion” look.
