If you want to wear a scapular, wear a scapular. A scapular means cloth over the shoulders, which, for the abbreviated versions, needs the two pieces of cloth. If you have only one cloth, then it’s not a scapular.So can I wear this scapular or not with the piece missing?
Just get some brown cloth and sew it onto the strings and you’re done. You have a scapular and the blessing transfers to it. Without the second piece, it’s just a badge.
