A description of clothing

“I’ve never been good at describing clothes but he was wearing overalls, blue-jean overalls, probably long-johns under them, I don’t know. Anyway, she was also wearing what I call a cowboy shirt, a long-sleeve button down shirt with pockets that close; pockets with a metal snap instead of buttons you put through a slit, maybe flannel, maybe jeans material, probably a type of cloth I don’t know the name of, the flaps over the pockets almost triangles with a white pearl button in the point of the flap and silver metal around the pearl and for the snaps too I assume. But you know what I mean? A cowboy shirt.”
