Denim 101: The History of Belt Loops on Jeans 👖 Belt loops weren’t always part of jeans. Before 1922, suspenders did the heavy lifting. From 1922–1937, jeans featured both belt loops and suspender buttons, letting wearers choose their style.⁠ In the 1940s, as denim production scaled, the back center loop was sewn over the center seam for durability. But by 1954, it shifted off-center—making mass production easier. Some vintage jeans even show unintentional offset loops from hand-sewn variations.⁠ By 1966, sewing technology brought the center loop back to its now-standard placement. Still, those quirks in vintage denim remain collector favorites, showing that even the smallest details in jean history tell a story.⁠ #details #selvedge #selvedgedenim #japaneseselvedge #madeinamerica🇺🇸 #rugged #ruggedstyle #americanbuilt #workwear #craftsmanship #vintage
