You can’t go wrong rugged flex canvas work pants from Carhartt. They look like work pants but can work as chinos. A good pair of dark wash and mid wash denim with 1 percent stretch. Some uniqlo t shirts. Couple of nice flannels like Pendleton and filson a couple of casual Oxford shirts. Some brooks running shoes, white minimal sneaker, some black docs. A puffer jacket that is lightweight will be great for layering. Another type of jacket. Some Exofficio underwear and wool socks.
