A greenish-brown, diamond-twill, boat-neck wool sweater woven between 230 and 380 and worn by a reindeer hunter was discovered by researchers in 2013. The tunic, which was mended with two patches, had been preserved in the Norwegian Lendbreen glacier and would have fit a slender man of about 5'9". “The hunter,” said researcher Lise Bender Jørgensen, “looked after his clothing.”

Julius Caesar was criticized for his loosely belted toga. “Beware the badly belted boy,” said Sulla; Cicero sneered at Caesar’s habit of “trailing the fringe of the toga on the ground like an effeminate.” His political rival Cato the Younger made a point of wearing a short toga with no tunic underneath, as was considered masculine. But a decade later it was common for young Roman men to grow goatees, wear flowing togas, and use “loosely belted” as a catchphrase.

When Amelia Earhart became the first woman to fly across the Atlantic as a passenger in June 1928, the New York Sun ran an article with the headline MISS EARHARD SPURNS FASHIONS: SHE CARES LITTLE ABOUT CLOTHES, DOES NOT USE LIPSTICK—LIKES TO FENCE AND DRIVE CAR. “Flying is a perfectly natural thing in her opinion,” it read, “and requires no special togs: a dress is as good air equipment as trousers.”

In 1876 Dr. Gustav Jaeger, zoologist and physiologist at the University of Stuttgart, began advocating the wearing of rough animal fibers, particularly undyed sheep wool, close to the skin; early customers of his “Sanitary Woollen System” included Oscar Wilde and Henry Stanley, who brought them on his expedition to Africa to search for Dr. Livingstone.
