Men’s apparel market size
In 2025, the global men’s clothing market is expected to make around USD 590.5 billion, and it’s set to grow each year by about 2.7% until 2029. The United States is the biggest contributor, bringing in USD 116 billion.
Casual wear is growing fast too. It was worth USD 12.3 billion in 2023 and is expected to reach USD 341.2 billion by 2031, with a strong yearly growth rate of 7.8%.
The figures clearly reflect that the men’s apparel industry will grow exponentially this year and beyond. Factors like changing consumer preferences and the influence of social trends have pushed people from formal to more casual attire.
Top 7 casual looks for modern men
1. Blue shirt with neutral bottoms
Blue shirts and neutral bottoms are a foolproof combo that never goes out of style. You can pair a classic blue button-down with navy pants for a sleek, put-together look. Or, wear beige or light khaki shorts to keep it casual and cool.
Neutral bottoms will let the blue take the spotlight. You can tuck the shirt in for a formal look or out for an informal appearance. The point is that this combo will always hit the mark when heading to brunch or sticking to a relaxed dress code at work.
According to Google Ads, the search volume for the term “neutral bottoms” rose to 12% in May 2025.
2. Contrast the tones
When in doubt, go for simple and elegant looks. For this, you can pair similar tones for a clean, put-together look. It is a classic American style that’s effortless but makes you look sharp.
There’s also an option to pair a light grey shirt with darker grey chinos for a modern, monochrome vibe. Or, how about mixing black pants with a charcoal tee for a sleek, low-key outfit that works everywhere?
Tone-on-tone dressing isn’t just stylish. It’s easy to pull off and hard to mess up. Plus, it gives you endless ways to play with color without stepping beyond the trends.
3. Cool denim and pants combo
Pairing a denim jacket with pants is a simple move that adds a cool flair to everyday looks. And in 2025, it’s all about effortless style that works for every body type.
A jacket’s structured fit balances the pants’ relaxed shape, creating a vibe that feels casual but still sharp. Opt for dark, rich colors like deep indigo or black denim to create more polished looks. It’s a modern take on a classic look, while flexible enough so you can dress up or down depending on your routine.
According to Google Ads, the term “denim jackets” increased 7-8% from January to May 2025. The demand is likely to grow at the end of the year, when cold seasons hit.
4. Black with black
An all-black outfit is one of the classics for men and women both. This casual dress code, when done right, can look quite stunning. Like every other style above, it’s essential to pay attention to the details. A clean silhouette is key. Baggy, worn-out pieces can make the outfit look lazy rather than effortlessly cool.
Here’s a style tip: Mix in subtle shades like charcoal, navy, or deep gray to add depth while keeping that sleek, monochrome vibe. For example:
- Layer a dark jacket over black pants and a black tee for contrast.
- Pair black jeans with a charcoal crewneck for a softer variation of the look.
- To break up the outfit without losing its edge, throw in non-black footwear like white sneakers, tan boots, or even gray loafers.
When done right, black-on-black is one of the most Instagram-worthy styles to date.
5. Neutral tones, endless styles
Neutral tops and bottoms are a simple combination that works for pretty much any occasion. These shades won’t ever let people down, whether they’re dressing up or keeping it casual. For instance, warm blue paired with beige chinos, an all-white fit, or a dark wash with a light gray shirt can complement any skin tone.
The beauty of neutrals is how easily they mix and match, creating endless possibilities.
6. Knit tops and bootcut jeans
A lightweight knit top with bootcut jeans is perfect for a laid-back yet stylish look. Pairing a simple white t-shirt with these jeans creates a versatile outfit that works for various occasions. The relaxed fit of the bootcut balances well with the snug feel of a knit top, making it a versatile choice for warmer months.
The best part is that neutrals and subtle shades mix seamlessly with bootcut jeans. This gives endless styling options without any hassle.
7. Zipped sweaters
Zipped sweaters, especially half-zips, are making a strong comeback this year. They’re indeed a go-to for the modern man who wants to look sharp without trying too hard. Not to mention how you’re always ready to flaunt on Instagram. Here’s a quick style tip: Stick to cool tones like blues, greys, and neutrals to keep things clean and timeless.
Style them right following the tips below:
- Layer it over a fitted polo or white t-shirt
- Pair with dark-wash jeans or chinos
- Go for subtle textures or classic patterns
Zipped sweaters are an overlooked classic that combines comfort, function, and style. All of it in one easy outfit upgrade.
How to accessorize for a casual look?
Accessories are a fun and easy way to upgrade your casual outfits. They help show off your personal style and make even basic clothes look more put-together. You don’t need a lot. Just a few wise choices can make a big difference.
Here’s how to do it:
- Start with a watch or bracelet: These small details can add polish without trying too hard. Go for light and simple pieces in neutral or cool tones like blues—they’re easy to mix and match.
- Add pins or patches: A cool pin on your cap or jacket can show off your personality and spark conversation.
- Choose the right shoes and belt: Clean sneakers or casual loafers, paired with a matching belt, keep your look sharp.
- Don’t forget sunglasses: They give you instant brownie points and work well for Instagram-worthy casual shots.
The goal isn’t to overload. All it asks is to add one or two touches that reflect everyone’s unique personality. It’s all about keeping it light, easy, and true to your style.
