The problem with Wranglers is they have a big folded double-stitched seam on the outside of the leg that looks kind of clunky. Levis have either a double stitched seam that’s hidden on the inside of the leg (505) or single stitched on both sides (501).
Didn’t Levi’s also have the double-seam on the outside back in the 60’s and 70’s? I seem to remember that....
