I found some parts on a VHS. And there are at least 3 or 4 girls in 4 different shortalls and bibs and I now also found a woman, shirtless in bibs (48 yo Lindsay Wagner).
The light blue shortalls are maybe hickory striped, the other light blue shortalls on the main entry are checkered. Bibs of the chubby girl and the other shortalls are plain, faded blue, same as the woman’s.
Obviously many scenes (mainly shortalls). Also starring Ross Malinger (bot probably not in bibs).
Still rating 5. Main entry at
