‘Mandalorian’ Actor Played a Big Part In Designing His Own Costume
And he did a fantastic job!
The actor, Paul Sun-Hyung Lee, was able to flex his creative muscle not only in front of the camera but off-screen as well! On his personal Twitter, Lee responded to a comment about the flight jacket he was wearing in the last episode of The Mandalorian. In addition to being the same cut as an Indiana Jones jacket, the actor also sported some Rebellion division insignia patches, the classic Rebel Alliance Starbird on the left shoulder, as well as two unique designs on the front.
After crediting costume designer, Shawna Trpcic for creating such an inspired look, Lee revealed that Trpcic actually let him design the division insignia patches on the front of the jacket! Not only is that something that Star Wars fans and cosplayers will look at for inspiration for years to come, but it’s an honor for the actor himself to take a little more ownership over his role and costume:
