Shinya Mills knows their stuff. With Ace selvage, they recreated this selvage by analyzing a worn-in pair of jeans from the 50s. Uneven slubby yarns were standard during the 40s and 50s due to limited yarn-spinning possibilities. It may look crude or too rustic. But over time, washing and wearing reveal a chunky and beautiful salt and pepper texture. The result is amazing — a celebration of denim's imperfect perfection.
