Photographs from the United States before roughly 1965 tell a striking story of their own. A man in a full wool suit, hat tilted, polished shoes, walks into a grocery store. A woman in a tailored dress, gloves folded over her purse, steps off a city bus on a Tuesday afternoon. Crowds at a baseball game sit shoulder to shoulder, nearly every man wearing a collared shirt, a tie, and a fedora.

There was no dress code posted at the stadium entrance. No one checked at the gate. That was simply what you did before you went out into the world. Today, the same locations tell a different story.

Airports, courthouse lobbies, expensive restaurants welcome flip-flops, sweatpants, graphic tees, and pajama bottoms. Nobody blinks. The idea of dressing up for a flight, a dinner, or even a funeral feels to many under forty like a punchline from their grandparents’ era. The question is how a country that once treated getting dressed as a daily act of civic participation became a nation where comfort rules and the necktie is a relic.

The answer spans a full century, touching wars, recessions, cultural revolutions, corporate boardrooms, technological upheavals, and deliberate marketing campaigns. In the early twentieth century, clothing was a language. A complex, unspoken social code communicated who you were, where you came from, and where you believed you were going. A man in a three-piece suit announced his ambitions.

A woman in a tailored dress with matching hat and gloves participated in a shared ritual of presentation. Stepping outside your front door meant entering a space that belonged to everyone, and you owed that space a certain standard of appearance. This formality was not limited to the wealthy. Working-class men wore suits.

Factory workers wore pressed trousers and fedoras on their days off. Immigrants arriving with almost nothing understood that dress was their first visible claim to belonging. Photographs from Ellis Island show families in their finest, however worn or mended. The message was clear: I may be poor, but I am dignified.

I may be new here, but I take this seriously. The economics made formality accessible. Suits in the 1920s through the 1950s were relatively cheap compared to income. A working man could own two or three and rotate them through the week.

Clothing was built to last, repaired when frayed, passed down when it no longer fit. A good suit was an investment, not a trend. Culture reinforced this at every level. Schools expected a certain standard.

Churches required it. Offices demanded it. Even leisure, going to the movies, attending a dance, visiting a restaurant, carried implicit expectations. Hollywood amplified the message.

When Cary Grant moved across the screen in a perfectly cut charcoal suit, he set a standard, showing millions what elegance looked like and the subtle power that came with it. Women watched Katharine Hepburn and Grace Kelly and understood that beauty involved the entire silhouette, the intentionality of the whole presentation. The men who came home from the Second World War carried that formality into the booming postwar economy. The late 1940s and the 1950s represent the peak of everyday American formality.

Men wore suits to work, to dinner, to the ballpark. Women wore dresses and heels to shop for groceries. Children went to school in pressed clothes and polished shoes. Air travel was the ultimate expression of this culture.

Flying was expensive, rare, and glamorous. Passengers dressed as though attending a gala. The cabin was treated as a special space, and boarding a plane demanded your very best. Airports featured sit-down restaurants with white tablecloths and uniformed waiters.

Yet the first cracks were already forming. They came, as social change often does, from the edges. In the 1920s, flappers bobbed their hair, shortened their skirts, and scandalized their parents. It was the first real generational rebellion in American fashion.

More quietly, athletes in tennis, polo, and golf began wearing lightweight, breathable clothing designed for their sports. Wealthy Americans with leisure time wore these garments not just on the court but afterward, at lunch, at casual gatherings, on weekends. This was the birth of the casual exception, the idea that certain contexts relaxed the rules of formal dress. The country club, the weekend retreat, the beach vacation.

A small crack, but enough to let light through. The Second World War widened it considerably. Millions of men traded civilian clothes for military uniforms, wearing the same thing every day for years. Comfort and functionality were paramount.

When they came home, their relationship with clothing had changed. They still wore suits to the office, but at home, in the evening, on weekends, they were far more likely to change into something comfortable. The rigid boundary between dressed and undressed had begun to blur. The postwar economy also produced an explosion of new synthetic fabrics, nylon, polyester, rayon.

These materials were lighter, cheaper, more colorful, and easier to care for than wool, cotton, and linen. A man who once owned three suits could now own a closet full of different outfits for different occasions, and some occasions increasingly called for something less formal. The real revolution came from the children of those well-dressed postwar parents. The 1960s represent the hinge point in the entire story.

For baby boomers raised in immaculate 1950s households, formal clothing was not just fabric. It was ideology, the uniform of a system they increasingly viewed as hypocritical and oppressive. The civil rights movement exposed the brutal reality behind the polished facade of American respectability. The Vietnam War sent young men to die in a conflict millions believed unjust.

The first and most visible act of rebellion was refusing the uniform. Blue jeans became the fabric of revolution. Before the 1960s, jeans were strictly working-class, the pants of miners, farmers, and factory workers. No respectable middle-class person wore denim in public.

That was precisely the point. When college students and young professionals wore jeans deliberately, they were not making a fashion statement. They were making a political one: I reject your values, your wars, your corporate conformity, and the clothes that symbolize all of it. The hippie movement took this further with tie-dye, patched bell-bottoms, sandals, beads, and headbands, every element a deliberate inversion of the established order.

They lost most of their political battles, but they won the fashion war completely. By the early 1970s, mainstream Americans were wearing jeans and t-shirts to places where suits and dresses had once been mandatory. The decline accelerated through the 1970s and 1980s for reasons beyond cultural rebellion. The rise of suburbs eroded the old urban rituals of public presentation.

In a city, you dressed up because you were constantly visible among strangers who judged your appearance. In a suburb, you drove from your garage to a parking lot and into a climate-controlled building. Public space in the traditional sense barely existed. The workplace was transforming too.

As the economy shifted from manufacturing to services and then technology, corporate formality began to feel like an unnecessary constraint. Then came a moment that changed the American workplace wardrobe more than any cultural movement. In 1966, the Hawaiian Fashion Guild lobbied the legislature to allow state employees to wear aloha shirts on Fridays during summer. The custom, called Aloha Friday, was a hit.

Around the same time, the founders of Hewlett-Packard encouraged Blue Sky days, Fridays when employees dressed casually to think creatively. The idea spread through the emerging technology industry in Silicon Valley. But the casual revolution might have remained regional without a brilliant piece of corporate marketing in the early 1990s. Levi Strauss saw an opportunity.

In 1992, a Levi’s executive sent an eight-page booklet called A Guide to Casual Businesswear to roughly 25,000 human resource managers across the country. It promoted Dockers as the ideal Casual Friday garment, a marketing campaign disguised as a public service announcement. It worked spectacularly. Within a few years, a majority of American companies had adopted some form of casual dress policy for at least one day a week.

Casual Friday became casual everyday. Silicon Valley delivered the killing blow. The technology boom of the late 1990s and early 2000s created a new philosophy of work in which the old markers of corporate respectability were not just unnecessary but suspicious. Dressing formally signaled that you did not understand the culture.

Steve Jobs, with his black turtleneck and jeans, became the most visible symbol. Mark Zuckerberg, appearing before Congress in a gray t-shirt and hoodie, took it further. These men dressed casually because the casualness was the image, communicating that they were so successful they did not need to perform respectability. By 2019, even Goldman Sachs relaxed its dress code to business casual.

When Goldman Sachs tells employees they no longer need suits, the war is over. Technology, economics, and changing attitudes toward comfort drove casualization further. Air conditioning made formal dress in summer less a matter of survival, and paradoxically, the more comfortable environments became, the more people demanded comfort in clothing. The athleisure revolution engineered garments for maximum physical comfort, stretchy, moisture-wicking, lightweight.

Americans spent nearly $44 billion on activewear in 2015, up 16% from the year before. By the early 2020s, the global athleisure market exceeded $400 billion, and roughly 85% of Americans wore athletic clothing even with no intention of exercising. Meanwhile, fast fashion made clothing disposable. In 1977, clothing accounted for 6.

2% of American household spending. By the mid-2020s, it had fallen to roughly 3%. Americans bought more garments than ever but spent less on each, and clothing became a consumable, like a paper towel. The pandemic accelerated everything.

In early 2020, millions of Americans went home from their offices. Working from a kitchen table, attending meetings through a laptop camera, the suit became absurd. During the first two months of lockdown, men’s suit sales plummeted 80%. Brooks Brothers, the 202-year-old institution that had dressed forty presidents, filed for bankruptcy.

The pandemic did not create the casualization, but it removed the last barriers and normalized comfort as virtuous. When offices reopened, the old standards did not return. For most of human history, clothing marked social hierarchy. Sumptuary laws in Europe literally prohibited people from dressing above their station.

The American experiment rejected that system in theory, and the suit became the great equalizer, the uniform of the meritocracy. A man in a good suit could walk into any room and be taken seriously. But this depended on a shared consensus that formal dress mattered. The counterculture of the ’60s broke it ideologically.

The economic changes of the ’70s and ’80s broke it practically. The technology culture of the ’90s and 2000s broke it aspirationally. The pandemic broke it physically. What remains is a country where clothing has been almost entirely privatized.

It is no longer a shared language or public act but a personal choice, unbounded by collective expectation. In many ways, this is liberation. The old codes were rigid, uncomfortable, and exclusionary. But something has been lost.

There was a time when getting dressed was understood as a gesture of respect, not just for yourself but for the people around you, for the spaces you entered, for the occasions you participated in. You dressed up for church because the community mattered. You dressed up for a dinner because the host had made an effort. This was reciprocity, the recognition that your appearance was one way you maintained your social relationships.

The loss of this ethos is not just about clothing. It reflects a broader erosion of shared public standards, the elevation of personal comfort above collective consideration. Yet there are signs the pendulum may be swinging back for some. Younger men raised in the era of athleisure are discovering classic menswear and formal dress not as conformity but rebellion against a new norm.

Research suggests that dressing formally affects how you perceive yourself, leading to more abstract thinking, greater confidence, and better performance. Whether these trends amount to a genuine reversal is impossible to say. The forces that drove casualization are deep and powerful. The suit is not returning as the default uniform of daily life.

The fedora is not returning to men walking to the grocery store. But the question of what was lost when we stopped dressing up remains. It is not ultimately a question about clothing at all, but about what we owe each other, about the difference between freedom and carelessness, about the invisible threads connecting us to the people and places around us. When you pull on sweatpants to run to the store or board a plane in flip-flops, consider what your great-grandparents would have thought.

Their world was rigid and often unjust, and many old dress codes deserved to die. But they understood something largely forgotten. Getting dressed was not just about covering the body. It was about showing up.

It was a way of saying, without words, I am here. I am present. I am part of this.
