LOL a university study. Its as simple as it was protective over clothing wear nothing more nothing less. In industry farming construction you get into all sorts of fluids oils grease etc. Overalls were made larger to go over clothing and the bib made it less restrictive in shoulders to railroad roundhouse a sledge. The old coal fired steam engines the conductors came to work in there good clothes and threw the bibs over along with a coat because the would become covered in black soot. Railroad oilers the same to protect whats under. These overalls were rarely if ever washed. They hung in a convenient spot to throw on for work.
