BiB - Ariel in Ski Overalls
The second overalls in the special purpose overalls were ski overalls. Probably one of the area's with one of the highest percentages of people regularly wearing overalls (outside of work).
On these overalls I have tried to demonstrate how one could adapt a plastic front release buckle so that the wearer can't push them open. I glued a plastic plate over the top of the male part, so that you can't push the female part to disengage. A small hole in the plastic allows for a tool to push on the female part to open the buckle. Not very escape-proof perhaps, but the wearer does need some sort of tool that would fit through the hole and allows enough pushing against the spring of the buckle.
