Academic dress at the University of St Andrews involves students wearing distinctive academic gowns whilst studying at the University of St Andrews. Undergraduate gowns in Scotland were once common at all the ancient universities of Scotland, with each having its own distinctive style. St Andrews undergraduates wear either a scarlet gown if they are part of the United College and studying in the Faculties of Arts, Medicine and Science, or a black gown if they are part of St Mary's College and studying in the Faculty of Divinity.
