Carpenter jeans are the fall denim I keep seeing on people who dress well without trying. This edit pairs Another Tomorrow's carpenter pair with barrel-leg jeans from AllSaints and 12th Tribe, plus straight and wide-leg options from Ulla Johnson, Whistles and H&M. They all have room in the leg, which makes them easy to layer under a long coat. Dark denim is the shade I would start with.
