I would very much like to see, and hope a cardinal would, start a movement (by example as well as in the Council of Cardinals) to replace the historical regalia of medieval princes, with far more simple dress.  It would be a real and genuine sign of service and de-investing oneself of the long-gone imperial, monarchal Church.  And as a by-product, it would help stop the laughing in the back rows when the cardinals appear in their lace and bright red cassocks.  And the hats.  Above all, they would mirror what Pope Francis has been teaching us all by example for over three years now:  simplicity in living provides a richness of the soul.
