I have seen Norma a number of times in several productions from very conservative to WWII style. There is one thing I have never seen. Norma is a priestess who during the opera conducts two different religious ceremonies. What usually changes when one transitions from normal life to a religious ceremony and back again? One usually appears first in street clothes, followed by vestments, followed again by street clothes. Have I ever seen Norma appear in what would appear to be a ceremonial garment of any kind? No. This is why the actions always feel wrong. We need more than you telling us she is a priestess. We need to see it, too.
