Like on the side of the highway in the midwestern winter, or in a boat's engine room while sailing along a dangerous coastline.
With only two of us on this size boat traveling 1500 nautical miles, we tried to wear bright things JUST IN CASE because you don't have much time if you fall overboard
I have a couple other suits too but they were trophies won at various 2CV meetings in France -- for my "mechanical prowess" can't remember the French words
They don't all fit as nicely as they used to, thanks to me spending more time at the stove than under the car lately...
