The Bikini Story: Reard, the Molitor Pool and the Bans

The bikini was launched on July 5, 1946, at the Piscine Molitor, a public swimming pool in Paris, by Louis Reard, an automobile engineer who ran his mother's lingerie business. Micheline Bernardini, an 18-year-old nude dancer from the Casino de Paris, modeled it because no fashion model would. It took its name from Bikini Atoll in the Pacific, where the United States had carried out its first peacetime nuclear test four days earlier, and it took nearly twenty years to become ordinary beachwear.

The Atome came first

Reard was answering a rival. In May or June 1946 the couturier Jacques Heim relaunched a two-piece he called the Atome, after the smallest known particle, and advertised it as "the world's smallest bathing suit." Heim had first shown a version in 1932. Like every respectable two-piece of the time, its bottom covered the navel.

Louis Reard had watched women on the beach at Saint-Tropez roll down their suits to tan, and he cut his design to match. It was a string bikini of four triangles, two for the bra and one front and one back, made from about 30 square inches of fabric printed with a newspaper pattern. His slogan undercut Heim directly: "smaller than the smallest bathing suit in the world." He hired skywriters to carry it over the Riviera.

Bikini Atoll and a name never explained

The test that gave the suit its name was the opening shot of Operation Crossroads on July 1, 1946. Unlike earlier tests, it was open to the international press, so the word Bikini was on every front page that week.

Most retellings say Reard picked the name because he expected an explosive reaction. He never said so. Writers have offered several motives: the bomb, the exotic Pacific, the idea that his suit had split Heim's Atome. Reard did leave one line on record, that "like the bomb, the bikini is small and devastating," and Diana Vreeland later called the bikini "the atom bomb of fashion."

Micheline Bernardini at the Molitor pool

Micheline Bernardini posed at the pool holding a small box, about 5 centimeters on each side, into which the whole suit could be folded. The photographs traveled. The International Herald Tribune alone ran nine stories on the event, and she is reported to have received 50,000 fan letters, many from men. Reard applied for a patent fourteen days after the show and received number 19431. In later advertising he set his own standard: a two-piece was not a genuine bikini unless it could be pulled through a wedding ring.

Heim's Atome sold more suits at first. Reard's word won.

Who banned the bikini

The early bans are better documented than the popular lists suggest.

• France banned the bikini from its coastline in 1949.
• Spain, Italy, Portugal and Australia restricted or banned it.
• In 1951 Sweden's Kiki Hakansson was crowned the first Miss World in a bikini. Pope Pius XII condemned her, and from 1952 the contest switched to evening gowns.
• In 1951 a Bondi Beach inspector measured the actress Jean Parker's bikini and escorted her off the sand. In October 1961 more than 50 women were arrested at Bondi under a 1935 ordinance on swimsuit dimensions.
• In West Germany many pools and beaches refused bikinis through the 1950s and 1960s.

Earlier versions of this exhibit said the Vatican declared the bikini sinful in 1946 and that Belgium banned it. No source for either turned up. The papal criticism on record is the 1951 one.

Hollywood had its own rule. From 1934 the Motion Picture Production Code barred the display of the navel in American films, which kept the true bikini off American screens for years.

From Manina to Dr. No

Film did what the bans could not. In March 1953 a 17-year-old Brigitte Bardot wore bikinis in the French film Manina, la fille sans voiles, and the publicity was about her swimsuits more than the film; it reached American cinemas in 1958 as Manina, the Girl in the Bikini. Bardot was photographed in a bikini on the beach at Cannes in 1957.

In the summer of 1960 Brian Hyland's "Itsy Bitsy Teenie Weenie Yellow Polka Dot Bikini" went to number one on the Billboard chart. Playboy put a bikini on its cover in 1962, the year Ursula Andress walked out of the sea in a white bikini in Dr. No. In 1964 the first Sports Illustrated Swimsuit Issue put Babette March on the cover in a white bikini.

A Roman precedent and a lingerie descendant

The idea was older than Paris. A mosaic in the Villa Romana del Casale in Sicily, dated to about 286 to 305 AD and excavated in 1959 and 1960, shows women athletes lifting weights, throwing the discus and playing ball in bandeau tops and briefs. Archaeologists named the room the Chamber of the Ten Maidens. Visitors call them the bikini girls.

Reard sold swimsuits from a Paris shop for 40 years. He died in Lausanne in 1984, and his company closed in 1988, the year the bikini made up nearly 20 percent of American swimsuit sales. Its cut lives on in two drawers: the beach bikini bottom and the everyday bikini brief.
