"Bon Ton Lingerie Plastique and your frock - that's all!" "...does away with overlapping thickness of vest, girdle, brassiere, pantie or bloomer." No boning this must have been pretty daring. And not too popular since I can't find any other references for the name 'Plastique'. But maybe some of that was the cost. $12.50 in 1929 is about $168.00 today, a bit pricey. Found in McCall's Magazine, October, 1929.
Granted, this is low hanging fruit, everybody in 1972 looked pretty bad. But the poor guys got the worse of it. Especially if they were shopping from the Montgomery Ward catalog for Spring/Summer. Of course that begs the question...who shopped from a Montgomery Ward catalog anyway? But somebody did. And some guys looked like this.
