Dark Blonde Girl Posing In Summer Swimsuit Costumes

After this, bathing wear started to shrink, first uncovering the arms and then the legs up to mid-thigh. Collars receded from around the neck down to around the top of the bosom. The development of new fabrics allowed for new varieties of more comfortable and practical swim wear.
Due to the figure-hugging nature of these garments, glamour photography since the 1940s and 1950s has often featured people wearing swimsuits. This subset of glamour photography eventually evolved into swimsuit photography exemplified by the Sports Illustrated annual swimsuit issues.
The first bikinis were introduced just after World War II. Early examples were not very different from the women's two pieces common since the 1920s, except that they had a gap below the breast line allowing for a section of bare midriff. They were named after Bikini Atoll, the site of several nuclear weapons tests, for their supposed explosive effect on the viewer.
Through the 1950s, it was thought proper for the lower part of the bikini to come up high enough to cover the navel. From the 1960s on, the bikini shrank in all directions until it sometimes covered little more than the nipples and genitalia, although less revealing models giving more support to the breasts remained popular. At the same time, fashion designer Rudi Gernreich introduced the monokini, a topless suit for women consisting of a modest bottom supported by two thin straps. Although not a commercial success, the suit opened eyes to new design possibilities. In the 1980s the thong or "tanga" came out of Brazil, said to have been inspired by traditional garments of native tribes in the Amazon. However, the one-piece suit continued to be popular for its more modest approach.
