It wasn’t long ago when most men with office jobs seemed to have closets full of dress shirts — solid, striped, plaid, polka dot.

Even as the ways of wearing them have become more casual in recent decades, even after the neckties they were often worn with have largely disappeared, collared dress shirts — whether button-up or button-down, tucked or untucked — have long remained a fixture of white-collar wardrobes.

The shift to working remotely during COVID-19 pandemic lockdowns eliminated the need for many to dress up for work. And when people started returning to the office, a lot of men left their dress shirts at home — a habit that has seemingly persisted as other aspects of office culture have returned.

But lately, as various companies have doubled down on their continuing efforts to get more workers back in offices, some at the forefront of fashion see signs of the dress shirt’s reemergence.

Nick Paget, senior menswear strategist at WGSN, a trend-forecasting agency, said a style trend known as “office-core” or “corp-core,” essentially a form of white-collar cosplay, has helped rekindle an interest in the garment. He added that dress shirts had not exactly been abandoned — more like reconsidered.

These days, dress shirts are being retooled to reflect a preference for working in comfortable clothes. Versions are being made of fabric blends that incorporate cotton and stretch materials, such as spandex, said fashion designer Todd Snyder, 57, who worked at Ralph Lauren and J. Crew before starting his namesake menswear label.

“In the early 2000s, we’d never look at stretch fabrics, but now men want to move,” Snyder said.

While the quintessential dress shirt — the kind often made of cotton in a poplin or twill weave — is by no means extinct, its halcyon days may be behind us, said Sean Estok, who oversees men’s tailored clothing and shoes at Macy’s department stores.

“Customers aren’t buying four dress shirts at the same time anymore, they’re refreshing one or two,” Estok said. “They don’t need a closet to have 50 different dress shirts like they once did because office life is not the same.”

Jim Moore, GQ’s creative director at large, described the ’80s as a golden age for dress shirts that was heavily influenced by the wardrobes of financial types associated with that time.

“The ’80s are really ruled by Wall Street and the stock market,” he said. “You’d meet with your doctor and have a suit on. Everyone had a suit on.”

By the end of the 1990s, the focus on Wall Street wardrobes had been eclipsed by an interest in the relaxed attire favored by office workers of another kind — employees of what were then known as dot-com companies.

In the 2000s and early 2010s, brands like Band of Outsiders and Thom Browne helped generate a new interest in dress shirts, with modern versions in playful patterns and shrunken proportions. As did the television show “Mad Men” and its 1960s-era wardrobes, said Michael Fisher, a senior vice president at Fashion Snoops, another trend-forecasting agency.

But that moment had begun to fade even before the start of the pandemic, as a growing focus on streetwear — the hoodies, T-shirts and sneakers favored by rappers and Silicon Valley types — pushed the office wardrobes of many men back to a more casual place.

Purchases of dress shirts and suits are now often tied to special occasions, such as weddings, said John Tighe, president of Tailored Brands, which owns Men’s Wearhouse and Jos. A. Bank.

“Today’s guy is looking for dress shirts to complete the look for his special event versus wearing one for work every day,” Tighe said. “There is more importance in comfort and performance.”
