Vintage Fifties Wear Well workwear coveralls. The fabric is a forest service/army green herringbone heavy twill. Patch pockets and an adjustable waist on the front of the waistband. Front metal buttons. A classic example of Fifties workwear. Stained and worn but still very solid with a lot of life left in them. Hit me up for more pics of the wear and tear. If they were anywhere close to fitting me, I would live in them. The are about 18″ across the waist and (maybe) about 19 1/2″ from waist to shoulder. (I have 19 1/2 written down with no explanation to it.)
