Thanks guys. It was for an 80s office party. Screen accuracy and filming sequence went out the door: instead I went for a mish-mash of the most identifiable and fun parts of the costume.
Yep - fabric paint and black tee. Looked into getting one printed and it was going to be a nightmare. If Indy Magnoli decided to do a run, I would be on it in a flash. ..Indy?
PS - Good luck to anyone trying to buy Lock Link Chain for the shoulder. No hardware supplier or importer in Australia had even heard of it and I ended using Long Link instead.
