Walk into any "Great Gatsby" themed party today and you'll see it. Polyester vests. Skin-tight trousers. Cheap plastic tommy guns. It’s a caricature. People think 1920s clothing for men was just about looking like a background extra in a mobster flick, but the reality was way more interesting—and honestly, a lot more comfortable than the stiff Victorian era that came before it.
The 1920s wasn't just a decade; it was a massive cultural exhale. After World War I ended, guys were tired of the rigid, high-collar formality of their fathers. They wanted to breathe. They wanted to dance. They wanted to drive cars without feeling like they were wearing a suit of armor. This decade was the literal birth of "casual" as we know it, even if their version of casual still involved a tie.
The Massive Shift in the Silhouette
If you look at photos from 1910, men look like vertical rectangles. Everything was narrow. By 1924, things started getting weirdly wide.
The "Oxford Bag" is the perfect example of this. Legend has it that students at Oxford University started wearing these insanely wide-legged trousers—sometimes with a 40-inch circumference at the hem—to hide their knickerbockers. Why? Because knickers were banned in some classrooms. It was a classic "stick it to the man" move that turned into a global fashion craze. These weren't just wide; they were cavernous. You’ve probably seen photos of Harold Lloyd or college kids of the era looking like they’re wearing sails on their legs. That was the height of cool.
It wasn't just the pants, though.
Suits became softer. Natural shoulders replaced the heavily padded look of the Edwardian period. For the first time, the "Sack Suit" became the standard. It was called a sack suit because it was literally cut like a bag—no waist seams, just a straight hang from the shoulder. It’s the ancestor of the modern American business suit. Brooks Brothers made a killing on these because they were mass-produced and actually fit a variety of body types without a week’s worth of tailoring.
Why 1920s clothing for men wasn't just black and white
Most of our mental images of this era come from grainy black-and-white film. We assume everyone walked around in shades of charcoal and soot.
Actually, the 20s were vibrant.
Think deep forest greens, rich burgundies, and chocolate browns. Patterns were everywhere. Stripes? Check. Windowpane? Check. Herringbone and Glen Plaid? Double check. A man in 1926 wasn't afraid to wear a pinstriped suit with a polka-dot tie and a pocket square that didn't match either of them. They were experimenting with color theory before that was even a buzzword.

Then there’s the texture.
Wool was the king. But it wasn't the lightweight, "Super 100s" wool we have now. It was heavy. It was scratchy. It was durable. A suit from the 1920s weighed three times what a modern suit weighs. This is why vintage collectors love this era; the stuff was built to survive a nuclear winter. Tweed was huge for the outdoorsy type, especially for the "sporting" look that became popular thanks to the Prince of Wales. He was the undisputed influencer of his day. If he wore it, every guy from London to New York was wearing it two weeks later.
The Rise of the Knickerbocker
Golf was the obsession of the 1920s. Even if you didn't play golf, you wanted people to think you played golf. This led to the explosion of plus-fours. These were trousers that buckled four inches below the knee, creating a baggy, gathered look.
They weren't just for the links. Men wore them for driving, hiking, or just hanging out at the local speakeasy. You’d pair them with argyle socks—the louder the pattern, the better. It was a way of saying, "I have leisure time." In a decade defined by the booming stock market (before the 1929 crash ruined the party), showing off your leisure time was the ultimate flex.
The Secret Architecture of the Shirt
Before 1920, collars were a nightmare. They were separate pieces of starched linen that you had to attach to your shirt with metal studs. They were stiff, they bit into your neck, and they were generally miserable.
The "Soft Collar" changed everything.
Initially, wearing a soft, attached collar was considered a bit "low class" or revolutionary. But once icons like Douglas Fairbanks started sporting them, the game was over. The "Arrow Collar Man" in advertisements became the symbol of masculinity, but even those ads eventually transitioned from the stiff, high-necked look to something more relaxed.
- Detachable collars didn't die instantly. They stayed around for formal business through the mid-20s.
- The Tab Collar used a little snap or button under the tie knot to pull the collar points together. This pushed the tie knot forward and up, creating a look of "perfection."
- Club Collars had rounded edges. They look very "Peaky Blinders" to us now, but back then, they were just a slightly more conservative, older-school option.
Shirt colors were rarely just white. Blue, pink, and lilac were surprisingly common. Often, the shirt would have a white collar but a patterned body—a look we now call the "banker's shirt."

Hats: The Non-Negotiable Accessory
You didn't go outside without a hat. Period. A man without a hat in 1924 was like a man without pants today. It just didn't happen.
But the type of hat you wore told the whole world exactly who you were.
The Fedora was the workhorse. It was versatile. But if you were a working-class guy or just "off the clock," you wore a Newsboy cap (often called an eight-panel cap). These weren't just for kids selling papers. Wealthy men wore them for driving their new Ford Model Ts.
In the summer, the Boater hat reigned supreme. Made of stiff straw with a ribbon, it was the "official" hat of the rowing clubs and summer picnics. Then there was the Panama hat—softer, more expensive, and perfect for the humid heat of a Gatsby-style Long Island summer.
The Bowler (or Derby) was still around, but it was starting to feel a bit "old man" by the mid-20s. It was the hat your grandfather wore to his banking job. The youth were moving toward the Fedora and the Homburg.
Footwear and the "Spectator" Revolution
Shoes in the 20s were a work of art.
The most iconic shoe of the era is the Spectator. Usually two-toned—white and brown or white and black—it screamed Jazz Age. It was flashy. It was daring. It was also incredibly hard to keep clean, which again, signaled that you didn't have to do manual labor.
For the everyday man, the "Oxford" was the standard. It looked a lot like the Oxfords we wear today, but the toe boxes were often more bulbous or "capped." Wingtips were also gaining massive popularity.

One thing people forget: Spats.
Those white or grey cloth covers that went over the shoes? They were actually functional. They protected your shoes and socks from mud and dirt in an era when many streets were still not paved. By the late 20s, they were becoming a bit of a fashion dinosaur, mostly worn by older, wealthy men or for very formal weddings.
What Most People Get Wrong About Formalwear
When we think of 1920s formalwear, we think of the tuxedo. But in the early 20s, the "Tailcoat" was still the boss for "White Tie" events. If you were going to the opera or a high-society ball, you wore tails.
The Tuxedo (or "Dinner Jacket") was actually the casual alternative for evening wear. It was "Black Tie."
Younger men loved the tuxedo because it was less restrictive. They could dance the Charleston without the tails of their coat flying into people's faces. By 1928, the tuxedo had pretty much won the war for evening dominance among everyone except the ultra-traditionalists.
Actionable Ways to Wear 1920s Style Today
You don't want to look like you're wearing a costume. To pull off 1920s clothing for men in the modern world, you have to pick and choose elements rather than doing the full "cosplay."
- Look for a wider leg. We’ve been stuck in the "skinny suit" era for a decade. Moving toward a straight-leg or slightly wider trouser with a higher rise (sitting at your actual waist, not your hips) is an instant nod to the 20s.
- Invest in a knit tie. Square-bottomed knit ties were huge in the 20s. They add texture and look great with a blazer.
- The "Spearpoint" collar. If you can find a shirt with longer, narrower collar points, you’re hitting that mid-20s aesthetic perfectly.
- Fabric choice. Swap your thin, shiny wool suits for something with "tooth." A heavy flannel or a rough tweed instantly gives off that vintage vibe without looking like a theater prop.
- The waistcoat. Wear a vest, but make sure it’s short enough that your shirt doesn't peek out between the vest and the trousers. That’s a common modern mistake.
The 1920s was about a specific kind of confidence. It was the first time men really started to dress for themselves rather than just for protocol. It was messy, it was experimental, and it was loud.
If you want to dive deeper into the actual history, look up the "Apparel Arts" illustrations from the era or check out the archives of the Fashion Institute of Technology. You'll see that the reality of the Jazz Age was much more diverse than any movie makes it out to be.
Stop buying the "1920s Costume Set" on Amazon. Go find a vintage-inspired wool coat, get some high-waisted trousers, and wear a hat because you want to, not because it’s a theme party. That’s how you actually honor the style of the 1920s.
