When was the trouser zip invented invented?

Answer 1

The trouser zip, or zipper, was invented in 1851 by Elias Howe, although it wasn't widely adopted for clothing until later. The design was further developed by Whitcomb Judson in the 1890s, who patented a clasp locker for shoes. The modern zipper as we know it was popularized in the early 20th century, particularly after its use in the 1913 design of army uniforms.
