Regarding the bathing suit, nary a navel was on display before the 1960s. In our own magazine’s documentation of the swimsuit, the 1940s brought us colorful images of mostly covered-up young ladies by the sea. Photos taken by Horst P. Horst and Toni Frissell showcase waist-hugging one-pieces with brief-cut bottoms. A decade later, bathing beauties reached impossible heights of elegance with swimwear almost too pretty to swim in. Some suits from the ’50s contained as much boning as a Dior gown, and a day by the pool required a coordinating sarong, hat, and pair of sunglasses.
