The English Cut creates a flower loop on the back of a lapel.  This little loop of thread is intended to hold the stem of a flower which has been threaded through your lapel buttonhole.  Your tailor can add one, too.  Mine charges me maybe three or four dollars.  If your lapel buttonhole is non-functional, your tailor can cut it and re-bind the edges, a service that won’t cost you more than about ten bucks.
