10 Swimsuits That Show How Swimwear Evolved Over the Decades

One of the first female swimsuits ever made were called, “bathing costumes.” It all began in the early 1800s. Swimwear fashion over the years has shown all sorts of collections, from the long and modest to the short and leggy. A quick dive into the decades will show you how we’ve gone from bathing gowns to bikinis.

1. 1800s

The 1800s marked the start of women’s swimwear. Most of what the women wore for a dip back then was long and modest. The swimsuits were also worn with belts to complement the silhouette at the time.

Bathing suits were made of either wool or flannel, which could prove difficult to swim in because of its heavy weight when wet. 19th century women donned on socks and shoes along with their bathing costumes to protect their feet from rocks and seashells lurking under the water.

2. 1900-1910s

The start of the 20th century saw a move towards a tighter fit. This movement was revolutionized after women were allowed to compete in the Olympics, particularly the one in 1912. Famed Australian swimmer, Annette Kellerman, sparked this start when she wore a short-sleeved tight bodysuit and sewn stockings.

3. 1920s

During the 20s, swimsuits began to expose more leg. They were becoming much shorter and form-fitting, showing off a curvier silhouette. That’s not all.

Swimsuits were also changing fabrics, from stuffy and thick wool, to rayon and light silk materials. Rather than solid colors, the fabrics were also donned with more fashionable stripes.

4. 1930s

Women in the 30s were experimenting with tanning and fashion designers were listening. Elsa Schiaparelli in 1932 came out with a backless design made with a built-in brassiere. That way, women can remove the straps and avoid tan lines.

In addition, legs were getting a bit more exposure with higher cuts. Designs with bows and collars were also becoming more prominent.

5. 1940s

Bye-bye straps, hello strapless swimsuits. The 40s were making way to bolder swimsuit looks. To secure the strapless swimsuit, designers had built-in bras. Women also loved wearing skirted cuts where a panel was sewn at the front to give the illusion of a skirt. In the European side, French designer, Louis Réard, designed the timeless bikini.

6. 1950s

During the late 40s, women had yet to embrace the bikini, but by the 50s, everyone wanted this hot new two-piece. But they weren’t the bikinis we know and love today. Instead, the bottoms were at a higher cut, near the belly button. Playful polka dots were also on-trend.

The 1952 Manina, the Girl in the Bikini star, Brigitte Bardot, gave a push to normalizing the bikini movement in Europe. The movie featured the actress wearing a strapless black swimsuit.

7. 1960s

The ’60s saw big-name designers like Ungaro and Calvin Klein diving into ready-to-wear swimwear, making stylish suits more accessible. Rudi Gernreich shook things up with his infamous monokini, a topless one-piece with high-waisted bottoms and skinny straps that blurred the line between modest and daring.

Though the original design was more of a statement than a trend, it inspired plenty of bold, strappy styles. The monokini became a symbol of the era’s rebellious spirit, even if it was too radical for most to actually wear.

8. 1970s

The ’70s brought barely-there bikinis in simple cuts and playful patterns, throw on some oversized sunglasses, and the look still feels fresh today. Thanks to Star Wars, metallic swimsuits in gold and silver blew up, with Carrie Fisher’s Princess Leia inspiring a futuristic trend. Earthy tones and asymmetrical one-pieces kept things stylish, while Farrah Fawcett made waves in her iconic red high-cut suit.

9. 1980s

The ’80s turned swimwear into a high-energy fashion statement with bright colors, wild prints, and sporty silhouettes, think tankini tops paired with high-cut bottoms for maximum leg. Baywatch skyrocketed the red one-piece to fame in 1989, making it an instant beach classic.

10. 1990s

The ’90s kept the high-cut legs from the ’80s but added daring cutouts, making one-pieces just as flattering as bikinis. Thanks to new fabrics, tan-through swimsuits let sun worshippers get that bronzed Baywatch look without fully stripping down. Tankinis blew up by the late ’90s, offering a sporty yet stylish option with square necks.

Now vs. then

From the 1800s wool “bathing costumes” to today’s barely-there bikinis, swimsuits have done a complete 180. Today’s swimwear is all about choice, letting every woman rock exactly what makes her feel confident and comfortable.

Each decade pushed boundaries, whether it was the scandalous monokini of the ’60s or Farrah’s iconic red one-piece in the ’70s. Today, swimwear is more diverse than ever. Just check out some of this season’s best swimwear here.
