Here's a pic of something similar.
Believe it or not, there was a time when I was thinner and could actually wear your Dad's jeans and jean jacket. I wore that jacket until it fell apart, I wrote on it with black permanent marker, all sorts of stuff, the lining came out. Here's a pic that's a little bit like the jeans. They pockets snapped up or down and were different colors like the jacket. I could wear them too.
The challenge was for him to figure out what to do next. I believe he might have lived with his buddy J (maybe this was before he left for the Army) for a while and he worked at Mosquito Control. I remember him saying that some of the guys would walk into the convenience stores and fill their waders with food. I don't know if your Dad stole or not. I do know that he was just living a very subsistence life, his biggest concern was getting enough to eat and it's hard when you're bouncing around quite a bit.
