Final answer:
Corduroy jackets were not adopted in a specific year; they evolved over time as part of fashion trends and textile technology, unlike the patenting of the zipper in 1893, which had a specific invention year.
Step-by-step explanation:
The adoption of corduroy jackets is not captured by a specific year as it was not an event like the patenting of the zipper in 1893, which had a distinct moment of formal invention. Unlike the zipper, clothing items like the corduroy jacket emerged gradually as part of fashion trends and textile technology developments over time. However, corduroy as a material has been around for centuries, and its popularity has waxed and waned throughout this period. The mention of textiles weaves a connection through history, from the practical and functional garments like those worn by "Ötzi" for survival in cold climates, to the ceremonial and powerful hunting coats of the Naskapis peoples, to the everyday utility and fashion of items such as corduroy jackets.
