I did some research and bathingsuits and when they became to be a fashion statement”
What I discovered was that In 1907 the swimmer Annette Kellerman from Australia visited the United States as an "underwater ballerina", a version of synchronized swimming involving diving into glass tanks. She was arrested for indecent exposure because her swimsuit showed arms, legs and the neck on a Boston beach for indecency -she was wearing one of her fitted one-piece costumes.
Kellerman changed the suit to have long arms and legs and a collar, still keeping the close fit that revealed the shapes underneath. She later starred in several movies, including one about her life.
It also seems that glamour photography in 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.
So the word Bikini comes from an island called Bikini Island which is well-known for being the subject of nuclear bomb tests, and because the bikini swimsuit was named after the island in 1946. The two piece swimsuit was introduced within days of the first nuclear test on the atoll, and the name of the island was in the news.
It's always nice to know some history of swimwear modeling
