Why is "Academic dress of the University of Cambridge" trending?

Wikipedia Overview

The University of Cambridge has a long tradition of academic dress, which it traditionally refers to as academical dress. Almost every degree which is awarded by the university has its own distinct gown in addition to having its own hood. Undergraduates wear college gowns, which are all subtly different; these differences enable the wearer's college to be determined. Academic dress is worn quite often in Cambridge on formal, and sometimes informal, occasions, and there are a number of rules and customs governing when and how it is worn. Black gowns (undress) are worn at less formal events, while on special occasions full academical dress is worn, consisting of gown, hood and headdress with doctors in festal dress. The university's officials also have ancient forms of academic dress, unique to the university.
