It is worn to chapel services, formal dinners in the halls of residence, meetings of the Union Debating Society, by student ambassadors who give guided tours of the University to visitors and by a few to examinations.
Graduates may continue to use either the academic dress of their earlier degree or the newly introduced St Leonard's College gown.
The description of their academic dress in full:[6] Undergraduate students in the United College (in full, United College of St Salvator and St Leonard), who are members of the Faculties of Arts, Medicine, and Science wear a scarlet cloth gown of knee length with open sleeves half the length of the gown and a burgundy velveteen collar.
It was introduced so as to better integrate those postgraduates whose original universities do not have academic dress into the gown tradition at St Andrews.
Gowns and caps appropriate to a person's degree or official position within the university are worn according to the rules set down by the Senatus Academicus.
[18][6] Hoods of graduates in all faculties are in a modified London pattern, with rounded corners to the cape and an angled liripipe.
Additionally, the President of St Mary's College is entitled to wear a graduate dress gown with lace adornments on the sleeve and purple silk lapels.
The gown has the shield of St Mary's College on the left breast in fine stitching and bronze filigree.
