Actor Joseph Gordon-Levitt tweeted some of Ralph McQuarrie’s original Chewbacca designs for A New Hope earlier this week, which Mark Hamill retweeted.
Chewbacca was almost forced to put on a pair of pants in A New Hope.
The Star Wars franchise isn’t exactly centered on Chewbacca, so it probably really would not have mattered what he was wearing, or even what he looked like.
The Star Wars universe would have been pretty weird if Chewbacca had pants on, though fans probably would have never said anything about it if it was all we ever knew.
