Academic dress at the University of Glasgow is worn at ceremonial events throughout the academic year. This primarily entails graduations, but includes Commemoration Day, church services, and the installation of Chancellors and Rectors of the University. The academic dress of all members of the University of Glasgow, including students, is regulated by the University Regulations. It shares many similarities with the other ancient universities of Scotland, most conspicuously that, unlike in the rest of the United Kingdom, headwear is only very rarely worn. Academic dress has been worn in the University of Glasgow since medieval times
