Another idea I have played with is cutting a cassock down to normal shirt length to wear with a kilt, cassock shoulder cape, and biretta. Of course, it would be an Anglican style, wool cassock (as opposed to a Roman style with the bottons down the center front). Do either of you (David and Bill) think that could work properly?

BTW, I guess we speak to what we are used to. My cassock has a collar opening of only two inches, but David is quite correct in stating the opening can be up to 4".
