The 1920s changed the way men dressed for everyday life.
Suits were still an important part of a man’s wardrobe, but casual clothing was becoming more common as people enjoyed new forms of entertainment, sports, travel, and outdoor activities.
Men began choosing softer sweaters, relaxed trousers, sports jackets, knitwear, and comfortable shirts for occasions that did not require formal dressing.
This new approach made 1920s men’s fashion more flexible without losing its neat appearance.
In this guide, you will find what men wore casually in the 1920s, from everyday trousers and shirts to sweaters, plus-fours, caps, and casual shoes.
The Rise of Casual Men’s Fashion in the 1920s
The 1920s brought a more relaxed attitude toward clothing.
After World War I, men were less interested in the extremely stiff styles associated with earlier decades. Everyday activities also changed as sports, cinema, dancing, automobiles, and outdoor recreation became more popular.
These activities created a need for clothing that allowed men to move more easily.
A man did not always need a formal three-piece suit.
For casual occasions, he could wear a sweater with trousers, a sports jacket with a shirt, or knickers with a flat cap.
This growing choice helped create the foundation for modern casual menswear.
What Did Men Wear Casually in the 1920s?
Casual 1920s men’s fashion was still neat and well put together.
Men commonly wore:
- High-waisted trousers
- Knickers and plus-fours
- Button-up shirts
- Sweaters and cardigans
- Sports jackets
- Vests
- Suspenders
- Flat caps
- Newsboy caps
- Leather shoes
- Two-tone shoes
The exact outfit depended on the activity and setting.
A man going to a sporting event could dress differently from someone spending a relaxed afternoon in the city.
1920s Men’s Casual Trousers
Trousers were an important part of everyday clothing.
Unlike many modern trousers, 1920s styles were generally high-waisted and roomy through the legs.
Wool and tweed were common choices because they were durable and comfortable.
Men often used suspenders to hold trousers in place instead of relying on belts.
For casual occasions, trousers could be worn with a simple shirt, sweater, or sports jacket.
Gray, brown, tan, and other neutral shades made it easy to combine different pieces.
Knickers and Plus-Fours
Knickers became strongly associated with casual and sporting clothing during the 1920s.
They were shorter trousers that usually ended below the knee and were worn with long socks.
Plus-fours were similar but extended several inches below the knee, giving the legs more room and making them useful for sports.
Men commonly wore these styles for:
- Golf
- Hiking
- Outdoor activities
- Country trips
- Casual weekends
A typical outfit could include plus-fours, a shirt, sweater, long socks, and a flat cap.
This look was practical but still had the polished appearance expected during the decade.
1920s Casual Shirts
Shirts were another important part of everyday clothing.
White remained a popular choice, but casual shirts could also feature soft colors, stripes, checks, or subtle patterns.
Men often wore button-up shirts with trousers or under sweaters.
For relaxed settings, the shirt did not always need to be combined with a complete suit.
A simple shirt and high-waisted trousers could create a clean everyday outfit.
Collar styles also changed during the decade.
Detachable collars remained common in the early 1920s, while softer attached collars became more popular as men looked for greater comfort.
Sweaters and Cardigans
Sweaters became increasingly useful for casual dressing.
They were practical for cooler weather and could be worn during sports or leisure activities.
Common styles included pullovers, V-neck sweaters, and cardigans.
A man could wear a sweater over a collared shirt and combine it with high-waisted trousers.
Cardigans offered another flexible option because they could be opened or closed depending on the weather.
Knitwear helped make casual clothing feel softer and less formal while still looking tidy.
1920s Sports Jackets
Sports jackets offered another way to dress casually.
They were less formal than matching suit jackets and could be worn with trousers in a different color or fabric.
Tweed was especially useful for this type of clothing because its textured appearance worked well with outdoor and country settings.
A simple combination could include:
- Tweed sports jacket
- White or patterned shirt
- High-waisted trousers
- Tie
- Leather shoes
This type of outfit allowed men to look smart without wearing a complete matching suit.
1920s Casual Vests
Vests were not limited to formal three-piece suits.
Men could also wear simpler waistcoats with shirts and trousers.
A vest added structure to a casual outfit while providing an extra layer during cooler weather.
Some men wore contrasting vests instead of matching them with their trousers and jackets.
This gave the outfit more personality without making it overly formal.
1920s Men’s Casual Hats
Hats were still an important part of everyday menswear.
Men commonly wore different styles depending on the setting.
Flat Caps
Flat caps were practical and popular for casual and working outfits.
They worked particularly well with wool trousers, sweaters, and sports jackets.
Newsboy Caps
Newsboy caps had a fuller shape and were often associated with working and outdoor clothing.
They provided protection from the weather while adding a recognizable vintage touch.
Fedoras
Fedoras could also be worn with less formal outfits.
They created a more polished appearance than a flat cap and worked well with jackets and trousers.
The hat often helped define the overall character of a casual 1920s outfit.
1920s Casual Shoes
Shoes were an important finishing detail.
Leather Oxfords and brogues remained useful for everyday dressing, while more distinctive two-tone shoes became popular for social and leisure activities.
For outdoor and sporting activities, men needed footwear that offered comfort and support.
The choice of shoes depended on the outfit and occasion.
A casual daytime outfit could look more relaxed with brown leather shoes, while black shoes worked well with darker clothing.
1920s Casual Sportswear
Sports had a major influence on men’s casual clothing.
Golf, tennis, boating, cycling, and other outdoor activities encouraged designers to create clothing that allowed greater freedom of movement.
Knickers and plus-fours were especially popular for golf.
Sweaters, shirts, caps, and comfortable trousers also became useful sportswear pieces.
These clothes did more than provide comfort.
They also introduced a more relaxed approach to everyday fashion that would influence later generations.
1920s Casual Fashion for Weekend Activities
Weekends offered men more freedom to move away from formal business clothing.
A man could leave his office suit behind and choose trousers, a sweater, sports jacket, and casual cap.
For outdoor trips, tweed jackets and sturdy trousers were practical choices.
For social activities, a cleaner combination of trousers, shirt, tie, and jacket could provide a smart but relaxed appearance.
The important difference was that casual dressing gave men more freedom to mix individual pieces.
1920s Working-Class Casual Clothing
Working men generally needed clothing that was durable and practical.
Simple trousers, button-up shirts, suspenders, work jackets, flat caps, and sturdy shoes were common choices.
Wool and heavier fabrics helped clothing withstand daily use.
The goal was not to create a fashionable outfit in the modern sense.
Comfort, strength, and function came first.
Even so, working-class clothing became an important part of the visual identity associated with 1920s men.
Casual vs. Formal 1920s Men’s Fashion
The difference between casual and formal clothing was clear.
| Casual 1920s Style | Formal 1920s Style |
|---|---|
| Sweaters | Tuxedos |
| Knickers | Three-piece suits |
| Plus-fours | Formal evening suits |
| Sports jackets | Dark tailored jackets |
| Flat caps | Fedoras and formal hats |
| Casual shirts | Dress shirts |
| Brown leather shoes | Polished formal shoes |
Casual clothing offered more comfort and freedom, while formal clothing focused on structure and presentation.
Both styles were important parts of 1920s men’s fashion.
How Casual Fashion Changed 1920s Men’s Style
Casual clothing did more than provide comfortable alternatives to suits.
It changed the way men thought about dressing.
A man could now choose clothing based on what he planned to do rather than wearing formal clothing for every occasion.
Sports, travel, leisure, and weekend activities all helped create this change.
The result was a wardrobe with more variety.
Men could still dress sharply while choosing clothes that suited a particular activity.
