I have looked and searched, but found no information on this, so I hope it's not something that everyone knows from posts decades ago. I have a question about a part of the RotJ costume seen in some of the promotional shots and some of the screen shots (but not all) from TDH's Gallery. If successful, you should be able to see the silver cord or pipe running under the left side of the chest armor and (in one shot) apparently down to the left thigh pocket highlighted in the photos I've attached to this post.
Any information will be greatly appreciated!!
