After Mademoiselle Bertin became dressmaker to Marie Antoinette, “all wished instantly to have the same dress as the queen,” wrote lady-in-waiting Jeanne-Louise-Henriette Campan. “The expenditure of the younger ladies was necessarily much increased; mothers and husbands murmured at it; some few giddy women contracted debts; unpleasant domestic scenes occurred; several families either quarreled or grew cool among themselves; and the general report was that the queen would be the ruin of all the French ladies.”

A king in twelfth-century-bc China enjoyed women wearing dangling pearls and jade in a “Hair-knot Which Sways at Every Step”; the emperor who built the Great Wall favored the “Hair-knot Which Rises Above the Clouds”; Tang women wore the “Hair-knot of the Homing Bird”; and a writer in the last years of the Manchu dynasty offered the name “Hair-knot of Disintegration and Homeless Wandering” for a style of the day. “The times are indeed out of joint!” he wrote. “I tremble to think of what is to come.”

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.

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.”
