Why do you wear black dinner suits, and carry little black bags?

The reason for this is quite simple. We wear dinner suits, because our meetings are conducted in a semi-formal and dignified manner, in keeping with our principles. Our members come from all walks of life, and the uniformity of our attire demonstrates our uniformity of respect for our fellow Masons. The small black bag we carry simply contains such items as our meeting notices and agendas etc, maybe a short speech and our Masons leather apron.
