Father Bill, it is 5yd wool. Yes I realize the tux jacket is all wrong, but I am sort of plucking at straws to find a way to dress as I originally intended. I am sadly no where near any urban centers. I am about 300KM east and north of Toronto, which makes find a rental very difficult. I am actually hoping that someone more knowledgeable about this region may have a suggestion where I might rent one. There are people in this board who know exactly where I am located and previously put me in touch with a local haggis maker who has now already been organized to supply haggis for 150. My jacket size for a conventional blazer is 44R, but I do not know how that translates to the shorter kilt jacket.
