A description of the hood lining used by the College of St. Thomas did not appear in Intercollegiate Bureau of Academic Costume (IBAC) lists from 1927 or 1948, but was first cited by Kevin Sheard in both Academic Heraldry in America (1962) and Academic Dress and Insignia of the World (1970) as purple with a gray chevron. A 1972 IBAC list had an identical description of the hood lining. It is not known whether this was a pattern that was actually assigned by the IBAC or merely a record of the college’s hood lining the Bureau borrowed from Sheard.
