Seder HaPragmatica.

“Women may not wear gold or silver, or colorful designs on their clothes… nor should men wear scarlet.” The regulations designate the amount of food permissible to be served at a wedding or a Brith Milah celebration, wherein, designated scholars, paid by the community, must deliver lessons in Torah. “No coffee or other beverages may be served at the festive meal during the night prior to the Brith - except to the “Lamdanim” (scholars). Only close relatives may send gifts to the mother who has given birth.” See S. Simonsohn, History of the Jews in the Duchy of Mantua (1977) p. 542.
