In the middle of the 20th century, many offices expected their employees to adhere to what modern workers would consider a formal look.

Companies back then were more "process-oriented" than the "results-oriented" organizations of today, according to The Atlantic.

Results-oriented organizations care about... well, results. According to Psychology Today, process-oriented companies are "concerned with how that success occurs."

As far as workplace fashion is concerned, that means that nowadays, many employers are thrilled as long as you're getting your work done. They care a little less about what you're wearing while completing said work.

Meanwhile, employees in the 1950s were largely expected to dress a specific way in a professional setting.

So what exactly did our buttoned-up office forebears wear to work in the 1950s and early 1960s?

Generally speaking, men sported suits, ties, and overcoats. "Dark suits, white shirts, dark ties, and white pocket squares didn't just dominate — they were practically a requirement in business," according to GQ.

And don't forget hats. Hats were a must for men on the go. "Regardless of what he wore, a properly dressed man in the 1950s still had to don a hat," William H. Young and Nancy K. Young wrote in the book "The 1950s."

Over the course of the decade, men's suits morphed from looser fits to a "skinny tailored fit style," according to the historical fashion blog Vintage Dancer.

Meanwhile, the Youngs wrote that career women typically wore "tailored wool suits over silk blouses." Dresses were also an option for the office. The standard look was completed with hosiery or stockings, as well as shoes with "thin stiletto heels."
Of course, while the 1950s are often remembered as a time of strict and widespread cultural conformity, not all workplaces were so exacting about dress codes.
Like today, a person's age, role, place of work, and personal preferences would influence how they dressed on the job.
And, while the following decade may have brought about cultural transformation, social upheaval, and hippies, significant changes to workplace fashion didn't happen overnight.

The beginning of the 1960s saw many Americans starting to take cues from the White House on how to dress. The Kennedy administration — with its preppy First Couple — ended up influencing the fashion of the time.

Fashion for men has traditionally been more conservative and less subject to change — especially when it comes to business attire. But suits did continue to slim out throughout the decade.

Over the course of the 1960s, women's office fashion would undergo both subtle and obvious changes. Lola Cherson, who worked in advertising in the 1960s, told The Atlantic, "Back then, we wore nice dresses."

She added that women would constantly check to ensure that the seams in their stockings were straight. Trousers in the workplace were still rare for women, although they were increasingly popular outside of work.

One fashion trend in particular took on special significance for career-oriented women. Pussy-bow blouses were viewed as a fitting equivalent to the traditional masculine suit-and-tie look. As outgoing Hewlett-Packard CEO Meg Whitman told PBS, "It was our attempt to be feminine but fit into what was then a male world."
The 1960s may have seen some major shifts, but the rollback of formality really began to snowball in the 1970s, as groovy fashions took hold across the country.

Of course, the prevailing dress code of a specific workplace was still largely dependent on the nature of the workplace itself. You'd notice major differences between, say, how people dressed in a newsroom and how people dressed in a bank.

Many employers continued to implement dress codes, but according to The Atlantic, "often-ignored infractions eroded the sanctity of any top-down policy."

As a result, style in the workplace began to reflect the everyday, far out fashions people gravitated toward.

The 1980s took workplace fashion trends to several tubular new extremes; an unsurprising development, given the decade's penchant for big perms, sequin-encrusted garments, and bright colors.

In the world of suits, broad-shoulders, bold patterns, and "power ties" ruled the day, according to Esquire.

Women in the workplace opted for what Newsweek described as an "exaggerated masculine style of dress," famously epitomized by shoulder pads. Towering high heels also allowed women to attempt to make up for any height differences with their male colleagues.

The "power dressing" trend for women carried over into the 1990s, but "the power suit started relaxing," according to Mic. Pantsuits became increasingly popular, as did low-heeled shoes.

Another trend that carried over from the 1980s was the rise of business casual. The Atlantic defined the initial iteration of the style as a combination of "khaki pants, sensible shoes, and button-down collared shirts," and marked Silicon Valley as its birthplace.

Silicon Valley proved to be the perfect breeding ground for the casual revolution, according to The Atlantic, given its interest in "discarding norms and celebrating rule-breaking." The look went mainstream in the 1990s.

For professionals who stuck with a more formal look, Esquire said nineties suits started out with a "loose, baggy silhouette" that transitioned into "a slimmer suit profile" by the early 2000s.

And, as always, workplace dress codes continued to fracture across industries, in terms of formality. Throughout the 2000s, "corporate image and employees' desires helped define who went casual and when," according to The Atlantic.
