(In the past only ceremonial clothing "specific to gender" was allowed, the outfits were known as known as subfusc, where male students were required to wear a dark suit and socks, black shoes, a white bow tie and a plain white shirt and collar under their black gowns, and female students had to wear a dark skirt or trousers, a white blouse, black stockings and shoes and a black ribbon tied in a bow at the neck.
Since 2012 the regulations have been amended to remove any reference to gender, so male students are free to sit their exams in said skirts and stockings and women have the option of wearing the suits and bow ties.
