Why is "Academic regalia of Columbia University" trending?

Wikipedia Overview

The academic regalia of Columbia University are the robes, gowns, and hoods which are prescribed by the university for its graduates. As one of the oldest universities in the United States, Columbia University has a long tradition of academic dress dating back to its founding in the 18th century, when it became the second university in the country to formally adopt academic robes. The development of Columbia's academic regalia has strongly influenced those of most universities in the United States. Since the passing of the Intercollegiate Code of Academic Costume in 1895, the style of academic dress worn at the university in the late 20th century has served as the basis of those of most other universities in the country. Though once worn daily by students at the university, caps and gowns now are only worn during commencement.
