Controversy erupted in Princeton, on and off the University campus, in the spring of 1931. The Undergraduate Council unanimously condemned some students who had been seen wearing denim overalls, because they looked too much like beer suits. “Yesterday’s spectacle of a few Juniors and a few Freshmen wearing light blue and dark blue overalls respectively…constituted an attempt to break down a privileged tradition of many years standing which belonged exclusively to the Senior Class.” Some of the underclassmen also bought matching denim jackets. Violence broke out on campus, with seniors attacking underclassmen wearing denim on Prospect Street. The juniors called their outfits “Applejackets.” The store that sold the clothes to the students was threatened, but owners vowed to sell overalls and jackets to whomever they liked in spite of the threats. This ad, which appeared in the April 16, 1931 issue of the Daily Princetonian, suggests how seriously the owners of the store that sold denim overalls to underclassmen took the threats they'd received from members of the Class of 1931.
