What did scholars wear in medieval times?

Answer 1

Medieval scribes were clerics, a word that came to be changed to clerks. They wore clothing similar to those of teachers, monks, or priests. That is to say the clothing was simple, somber, and neat. The cut would have been very conservative for the time and place, but that varied with time and place.

Answer 2

Throughout Europe (except, briefly in Ireland) scholars were male and attended Church schools. They were enrolled as "clerks in minor orders", meaning that they were already on the ladder of Church hierarchy - although at the very bottom of that ladder - and they dressed as clerics.

University students, for example, had their heads shaved in the Roman tonsure and dressed in a garment called cappa clausa. This was essentially a long, baggy, semicircular cloak sewn up the front to form a kind of full-length poncho with a hood attached; this might have short, wide sleeves, slits each side for the arms to pass through and/or sometimes sleeves that were not completely attached so they hung like pendants when not in use. Cappa clausa is Latin for "closed cloak".
