Heddels explains Arcuate (also Arcs)
From a legal sense, however, the classic double stitched arctuates or arcs that have become so recognizable originated with the very first Levi’s jeans. Acknowledged as the world’s oldest clothing trademark, the shape became synonymous with Levi’s jeans by 1900.
