Which later 19th-century invention mechanized the assembly of cut fabric into finished outfits?

Answer

Isaac Singer's patent of the sewing machine in 1851.

The industrial transformation extended past initial weaving and spinning into the finishing and assembly stages in the later 19th century. While William Perkin’s development of the first synthetic dye in 1856 advanced the finishing treatment of cloth, Isaac Singer’s patent of the sewing machine in 1851 directly addressed the assembly of cut fabric. This machine began to mechanize the process of turning prepared cloth into complete, finished garments, further separating the overall production pipeline from the traditional methods of manual tailoring and craftwork.
