When I was a young lad and saw these things in catalogues - they were still around, although on the way out - they were objects of absolute mystery. I had no idea why anyone would wear these things. What were those dangling straps for? Why so much stuff? What were foundations, anyway? That was the sign at the Sears and Penney’s stores: FOUNDATION GARMENTS.

Details: “Elastic top is lightly boned to prevent rolling up.”

“Rayon Power Net plus downstretch Rayon Satin elastic back trim hips and derriere.”

Translation: it feels so good when you get out of the damned thing.
