I never did any of that, but I did wear 29-32 501s and they were very tight. When I put a freshly washed pair on, walking was difficult until they relaxed a little. Back then, nearly everybody went commando, they didn't wear belts, and they left the button at the waistband and the bottom fly button undone.
The clone look was popular- very short, scissor-cut hair, 501s, Lacoste shirts and Adidas running shoes. It was a great look.
