Ted Crocker,

I just read your thread on jacket backs from April. Thank you. I believe you were referring to what they sometimes call a bi-swing, or action back- shooting coats and safari jackets sometimes have pleats behind the shoulders which allow fabric to pull out when needed, as when the wearer raises his arms to fire a shotgun. I believe the fabric returns (the pleat closes) based either on gravity or because of elastic strung between the pleats. If that is too complicated, one could probably find a jacket with a single inverted back pleat in the center, ( much like a box pleat on a kilt?) that would serve the same purpose. http://www.alexander-james.co.uk/arc...ducts/shooting . No rear views, unfortunately- just order a couple and see how they are put together. If you went with a contrasting color and maybe some piping, it could either look very smart or downright horrendous.
