I was wondering a few things about the historic place of various vestments in Anglicanism. I know stoles are allowed by the BCP, (but as I understand it tippets are more common) but can the color of the stole change with the liturgical season? I know copes are a required part of ordination garb, but are they allowed to be worn at any other time? Also, about headware: I realize that the practice among some bishops of sporting a mitre is largely a product of the Oxford movement (please correct me if I am wrong) but how did historical Anglicanism feel about other types of headware, such as birettas or Bishop Andrewes Caps? Thanks for your help.
