Were they Catholic, and did they get this from the Vatican... or is it something that has "always been done" in the Italian culture? It seems that the Italian women are channeling their sadness into their physical appearance, but I think of bereavement as more of a psychological process. Do these Italian women also have mood changes to go along with dressing in black until they die? What is there mental state during this time?
Just curious, don't waste your time answering if you need to study Micro.
