THIS VIDEO FROM THE OFFICIAL SITE. It's a trailer for the new reference book
Star Wars Costumes - The Original Trilogy which was released yesterday. This volume has photographed many of the OT costumes in painstaking detail. There are Rebel pilot helmets that have never been seen with such detail. The tiny intricacies of Vader's costume. And I'm sure there's probably a little bit about the infamous brown or blue coat worn by Han Solo in TESB.
Amazon.com currently has this book on sale for $37.95. And it looks impressive.
Most impressive.
