What inventor revolutionized ready-made clothing?

While there wasn't one single inventor who revolutionized ready-made clothing, Elias Howe's invention of the improved sewing machine in 1846 is widely credited as a crucial technological breakthrough that made mass production of ready-to-wear clothing possible. Before his invention, sewing was slow and laborious, making ready-made clothing expensive and impractical. Howe's machine dramatically increased efficiency, making mass production economically viable and thus leading to the rise of the ready-to-wear industry.
