These fresh-faced ladies of the 1920s modeled the current swimsuit garb of “modish jersey tank suits, curl-revealing caps and high two-tone shoes.” One can hardly imagine lacing up shoes for the beach or how much sand would enter them.
In contrast, the 2/7/55 LIFE compares the bleak, black tank/shorts of the past to the fashionable “sweater-girl bathing suits” of the present, with clinging knit, loud stripes, broad straps, skirts, and sleeves. Plus, they had the luxury of going barefoot.
Either way, the lesson here is to always have a cigarette handy, especially at the beach.
