Those little metal studs at the corners of your jeans pockets are rivets. They were added for a practical reason: pockets on work pants could tear where the fabric and stitching took the most strain. Rivets reinforced those vulnerable spots, helping the pants last longer.
A fix for hard-wearing pants
In the 1870s, tailor Jacob Davis came up with the idea of fastening metal rivets to work pants at points of stress. He partnered with Levi Strauss, who supplied his fabric, and the two received a patent on May 20, 1873. Their reinforced pants became the early blue jeans.
The problem was easy to recognize. A worker repeatedly reaching into a pocket—or carrying tools and other belongings in it—put pressure on the pocket opening. Stitching alone could give way. A rivet helped hold the layers of fabric together at the corner, where a tear was especially likely to begin. Levi’s describes the patent as an improvement to fastening pocket openings, not an invention of pockets or denim itself. You can read more about the original riveted blue jeans in the company’s account of its early garments.
Why the studs are still there
Look at a typical pair of jeans today and you can spot rivets beside the front pockets and often near the small watch pocket. They still serve their original purpose, even though most jeans now spend more time carrying phones and keys than accompanying someone through a day of manual labor.
It’s a small detail with a long history: a repair-minded solution became one of the most recognizable features of everyday clothing. Jeans aren’t the only garments that preserve old design choices. The opposite button placement on men’s and women’s shirts is another familiar detail with a history of its own.
