The Smallest Swimsuit in the World: The Bikini!

What better time to dive into the story of the bikini than August?
Life slows down, cicadas sing us through the afternoons, and while we’re dreaming of what’s next in September (and even more of next summer!), let’s take a moment to look back at this iconic piece of beachwear. We’re talking about the bikini—the ultimate “atomic” outfit.

For most of us today, choosing what to wear at the beach—one-piece, two-piece, or even three-piece—feels natural. But until the 1950s (not that long ago), it wasn’t like that.

As the idea of leisure time began to spread and seaside holidays became fashionable in the 1920s and ’30s, women began ditching heavy Victorian bathing dresses in favor of more fitted wool swimsuits. Yes, wool. These new styles followed the body’s shape more closely. But it wasn’t until the invention of Lastex—a shiny, stretchy synthetic fiber—that swimsuits truly hugged the figure, thanks to the fabric’s strength and elasticity.

Like many great inventions, the bikini has two “fathers”: French designer Jacques Heim and Swiss mechanical engineer Louis Réard.
In 1932, Heim created the Atome, which he described as “the world’s smallest bathing suit.” It revealed the hips but still covered the belly button with a horizontal strip of fabric. By the standards of the time, it was still pretty modest, and hardly anyone wore it.

Then came a pause in fashion history, brought on by World War II. But on July 5, 1946, the revolution was ready to start.
The mechanical engineer (and fashion enthusiast) Louis Réard officially introduced the bikini at the Molitor swimming pool in Paris. He named it “bikini” after Bikini Atoll in the Marshall Islands, where the U.S. had just carried out nuclear tests. He wanted his swimsuit to make an equally explosive impact.
Finding a model willing to wear it was no easy task—most thought it was far too scandalous. So Réard hired Micheline Bernardini, a nude dancer from the Casino de Paris. And it was a genius move.
Réard’s design was bolder than Heim’s: it was made for tanning, with two tiny triangles on top and two on the bottom, all held together with thin strings.
It was quickly labeled indecent and banned in several Catholic countries like Spain, Portugal, and Italy. Italy’s Interior Minister, Mario Scelba, even ordered police to patrol beaches to make sure women’s swimsuits met “standards of decency.” It was 1950.

But times were changing.
By the 1960s, with shifting social norms and the rise of youth culture, the bikini began to break free from all those restrictions. New fabrics, support from younger generations, and endorsement from Hollywood stars helped turn it from a symbol of scandal into a tool of female empowerment.
The real turning point came in 1962 with the James Bond film Dr. No. Ursula Andress emerging from the water in her white bikini sent shockwaves across the world. The scene became legendary—and in 2001, her bikini was sold at a Christie’s auction for £60,000.
