The term "white-shoe" originated in American English in the mid-20th century. It derives from the fashion trend among affluent Ivy League university students in the early 1900s, who wore white buck shoes as a mark of casual, preppy elegance. This specific sartorial choice became a metonym for the social class and conservative culture associated with elite Northeastern institutions. Over time, the adjective evolved to describe not just individuals but the traditional, exclusive, and often WASP-dominated firms in law, finance, and banking that were staffed by graduates from such backgrounds, connoting established prestige and sometimes old-fashioned propriety.
