“shape-insurance”…the Jantzen specialty of the house…makes these the most exciting swim suits of 1954. They mould you in beautiful lines, hold you in beautiful lines…when the suit is wet, when the suit is dry…and the shaping power goes on forever.
This Jantzen ad from 1954 is a great example of how swimwear is influenced by fashion. In the corseted 1950s, even your swim suit had built-in shaping. Imagine these suits with a matching skirt. You could go from the pool to the dance floor. And that’s a much nicer cover-up than an old tee shirt, wouldn’t you say?
