The history of swimwear: From bikinis to board shorts

The early days (circa 18th and 19th-century).

In the 18th and 19th centuries, modesty was all the rage—the less skin peeping out, the better. Women wore loose, ankle-length bathing gowns, often weighted at the hems to prevent any accidental exposure in the water. These designs were more for dipping one’s toes into the ocean (also known as ‘sea bathing’) rather than all-out swimming. 

In this era, swimwear was about conforming to strict social norms, leaving comfort, functionality, and self-expression by the wayside.

Functional fashion, here we come (circa 1900-1945).

As the 20th century began, so did a push toward functional swimwear. Swimming started gaining recognition as a sport, which meant a shift from restrictive bathing suits to more movement-friendly designs. Here, we meet Annette Kellerman, an Australian swimmer whose fitted, one-piece swimsuit caused a stir and even got her arrested for “indecency.” Oh, the horror! By challenging societal expectations, she paved the way for swimwear to go beyond mere modesty and begin blending functionality with personal style.

During this era, knitted swimwear also became popular, offering a bit of stretch while still keeping things modest—a nod to tradition with a step toward freedom.

The birth of the bikini (circa 1945-1999).

The trajectory of swimsuits changed forever. It was 1946 when the bikini made its debut. Introduced by designer Louis Réard, this two-piece design was initially scandalous—so much so that no model wanted to wear it, prompting Réard to hire a dancer instead. But as Hollywood icons like Brigitte Bardot flaunted the bikini on-screen, the look gained inevitable popularity, making bikinis a symbol of boldness and freedom.

Mid-century advancements in fabric technology, like Lastex yarn, introduced even more form-fitting options that stayed snug in the water. These developments made swimwear more practical and comfortable, setting the stage for the styles we know today.

Hello, modern swimwear (circa 21st century trends).

Today’s swimwear? It’s more inclusive, versatile, and stylish than ever (if we do say so ourselves). Here at Sheila, we create designs made with all body shapes in mind, celebrating people from every walk—and wave—of life.

Take our swim shorts. Once just loose, long board shorts for men, they’re now a go-to for women looking for both comfort and style. With flattering cuts and high-performance materials, they prove that, in swimwear, you really can have it all.

Yep, it’s official: no more dealing with bikinis that ride up, sag down, or create endless wedgies (someone had to say it). Our shorts offer freedom of movement, with high-waisted support, plenty of coverage, and length options to match your vibe. Jump in the ocean, jog down the boulevard, or pop into a Pilates session—our swim shorts can handle it all.

Plus, with advanced fabric tech like quick-drying materials and UPF 50+ sun protection, our swimwear is the perfect example of how history—and swimwear—keep evolving.
