Dress Codes of History: What “Casual” Used to Mean

What does it really mean to “dress casually”? Today, many of us reach for jeans or athleisure and think little of it. But a peek into the past reveals that “casual” once meant something very different—and what we wear (and why) is both a reflection and a driver of social change. To celebrate the quirks and history of casual dress, we’ve launched a new trivia game: Dress Codes of History: What “Casual” Used to Mean—a challenge to test your knowledge and spark conversation! But first, let’s unravel the history behind our evolving dress codes.

Defining “Casual” Across Eras

“Casual” is a moving target. In different eras, what counted as relaxed attire often looks surprisingly formal to modern eyes. From starched collars to polo shirts, the evolution of casualwear is a story of changing values, technologies, and identities. Understanding this helps us appreciate why certain clothes still carry social signals—and why “business casual” can mean a suit in one office and sneakers in another.

19th Century: Relaxing from Formality

In the 1800s, especially in upper-class Western society, strict formal dress codes reigned. For men, daily wear often meant frock coats, waistcoats, and top hats; for women, corsets, bustles, and heavy skirts. But as the century progressed, the idea of “casual” wear began to emerge—mainly for leisure, and mainly for men.

Did You Know?
- The lounge suit (ancestor of today’s business suit) was considered casual country or seaside wear when introduced in the 1850s. - For women, a “tea gown” was a radical, relatively unstructured garment worn only at home, out of public view.

The Roaring Twenties: Jazz Age Informality

The 1920s brought seismic social shifts—and with them, new approaches to casual dress. Flappers scandalized older generations by wearing short skirts and bobbing their hair. For men, plus-fours (baggy knickerbockers) became popular for sports and leisure.

Fun Fact:
- The “Polo shirt” was invented by tennis champion René Lacoste in 1926, blending sportiness with style. - Beach pajamas became the epitome of chic, relaxed wear for women vacationing at resorts.

Mid-20th Century: The Rise of Leisurewear

The postwar era saw a democratization of fashion and the birth of true “leisurewear.” After World War II, the lines between formal and informal blurred even further. Men began wearing short-sleeved shirts without jackets; women embraced pedal pushers and sundresses.

Fun Fact:
- The Hawaiian shirt (or “Aloha shirt”) exploded in popularity in the 1950s, symbolizing a relaxed, escapist spirit. - The T-shirt, once strictly underwear, became streetwear after WWII, thanks in part to Hollywood icons like Marlon Brando.

The 1970s and 80s: Denim, Rebellion, and New Norms

When denim jeans and T-shirts became mainstream, casual dress took on a rebellious edge. The counterculture movements of the 1960s and 70s made blue jeans a symbol of youthful freedom. By the 1980s, “Casual Fridays” began appearing in American offices, challenging traditional workplace attire.

Fun Fact:
- Levi’s blue jeans, first patented in 1873, were long seen as workwear before becoming a casual staple. - In the 1980s, designers like Ralph Lauren and Calvin Klein elevated jeans and casual shirts into high fashion.

Modern Interpretations: Business Casual and Beyond

Cultural and Social Influences on “Casual”

Dress codes don’t just reflect individual comfort—they signal belonging, status, and even rebellion. In some cultures, “casual” means removing a tie; in others, it’s wearing bright colors or traditional patterns. Social movements (like the women’s liberation movement or the tech boom) have also redefined which garments are considered “relaxed” or “appropriate.”

Fun Fact:
- In Japan, “Cool Biz” campaigns encourage office workers to dress lighter in summer—redefining business casual for a good cause (energy savings). - Hip-hop and streetwear have influenced global fashion norms, making sneakers and hoodies universally casual.

The Impact of Technology and Remote Work

The rise of remote work and digital meetings has sparked an unprecedented shift in dress codes. Video calls often require only a smart top, while pajama bottoms stay out of sight. The pandemic blurred work-life boundaries, further relaxing the standard of “casual.” But even on Zoom, subtle dress cues still help us communicate professionalism—or playfulness.

Fun Fact:
- Sales of “Zoom shirts” (easy-to-wear, camera-friendly tops) spiked in 2020 as remote work became the norm. - Digital avatars and virtual clothing are now being explored as the next frontier in casual self-expression.
