As we know, Rey has a characteristic three-bun hairstyle.
Now, to some degree, a (hair) bun is a bun is a bun, right? Well, except that most people wrap hair into a bun, and Rey's hair is actually three loops. You know who else in the Star Wars universe often had her hair in loops? Yup:
Do we have any indication about whether this similarity is purposeful rather than coincidental? Production notes or Visual Dictionary-type things? Has anyone interviewed the hairstylist for The Force Awakens?
Note that I'm NOT asking for an in-universe explanation for the hairstyle similarities. While it's doubtless possible to come up with any number of outlandish theories to explain how Rey would be copying someone who died 50+ years before she was born, it's hardly productive, and more to the point, it's not answerable. What I want to know is whether, out-of-universe, we have any reason to think this is more than mere coincidence. (Given what has been posted about the contents of the Visual Dictionary, the answer is looking like "no, it's just coincidence", but 1. I didn't know that when I posted this, and 2. I still hold out hope for a contradictory tidbit from an interview.)
Of course, if we get all conspiracy-theorist, the person who Rey really resembles is Sabé. Maybe Sabé and Obi-Wan did get it on, after all? :)
