Undergraduate gowns are a notable feature of academic dress for students at the ancient universities in Scotland. The most famous form of Scottish undergraduate dress is the red or scarlet gown. The gown is typically made of a thick woollen or wool-like material and is differentiated slightly according to the university at which it is worn. These gowns are worn by students of the University of St Andrews, Glasgow, Aberdeen, Edinburgh and Dundee. The University of Strathclyde did not adopt the red gown, and instead students use the black supertunica, adorned with saltire blue buttons and cords.
