Louis Réard, a French engineer-turned-swimwear designer, is credited with inventing the first modern bikini in 1946.

Quick Scoop

  • The modern bikini was unveiled by Louis Réard on July 5, 1946, at the Piscine Molitor swimming pool in Paris.
  • Réard named it “bikini” after Bikini Atoll, where the United States had recently conducted nuclear tests, to suggest it would cause an “explosive” reaction in society.
  • Earlier, designer Jacques Heim had created a similar, slightly more covering two‑piece swimsuit called the “Atome,” but Réard’s skimpier design exposing the navel is what became famous as the bikini.

A Bit Of Story

In conservative post‑war Europe, showing the belly button in public was shocking, so many professional models refused to wear Réard’s design. He eventually hired nude dancer Micheline Bernardini to model it, and her photos helped turn the bikini into an international symbol of bold, modern fashion.

Why It Mattered

  • The bikini challenged existing norms about women’s bodies and modesty, triggering debates about morality and fashion.
  • From the 1960s onward, it increasingly became linked with women’s liberation, personal freedom, and later body‑positivity movements.

TL;DR: Louis Réard is widely regarded as the inventor of the modern bikini, launched in Paris in 1946, even though similar two‑piece styles and rivals like Jacques Heim’s “Atome” existed just before.
