The Arcuate Stitch, which can be said to be the symbol of the 501 that has evolved over the years, has also undergone changes along with the background of the times.
The transition of the Arcuate Stitch specification is as follows:
1922-1941 Single thread cotton stitch
1942-1945 Painted stitch
1946-1969 Double thread cotton stitch
Stitch density: 6 stitches per inch
1970-2004 Double thread spandex stitch
Stitch density: 12 stitches per inch
Even now, the Arcuate Stitch continues to evolve in terms of stitch color and shape.
Attention is needed for the future changes as the symbol of Levi’s!
