A while ago, there was a thread on wearing kilts with academic regalia. I said I would post a pic next time I wore mine. Here it is. The regalia is the University Newcastle-upon-Tyne, Ph.D. The style is a Cambridge open doctor's dress gown with white and scarlet facing. The hat is a pileus quadratus (the forerunner of the mortar board).

I wear this regalia for convocations and graduations at the State University of New York, College at Cortland.
