I just got a $300 book in, DRESSING A GALAXY: THE COSTUMES OF STAR WARS. It will be available in my shop to any of our 501st/RL members, (or potential members), for costume research. It has in-dept descriptions, images, and even FABRIC SWATCHES of the actual costumes from Lucasfilms archives

! And I know sometimes one of the hardest things to find is that EXACT fabric for our costumes. Unfortunately it only includes the new Trilogy, not the original Trilogy costumes
