Thirteen years after women are allowed to compete in the Olympics, Carl Janzten introduces a two-piece bathing costume to enhance their performance. It's really just shorts and a T-shirt but tight-fitting enough to cause a bit of a scandal. In Europe, women start wearing bathing outfits that reveal a sliver of skin at the waist, and suits shrink stateside as fabric is rationed during World War II. For the most part, hems are shortened and skirts eliminated, but in some cases they do split into two. With the war over and spirits soaring, Parisian designer Jacques Heim, who works mostly with fur, debuts the atome —the world's smallest swimsuit. Showgirl Micheline Bernardini debuts the suit at a popular swimming pool in the center of Paris.
