What are the summer trends for casual outfits? A must-see for fashionable men in their 20s and 30s!

In order to wear men's casual outfits in style, it is important to incorporate trends into your outfits. In particular, men's outfits in the summer require some ingenuity because they cannot be covered with outerwear such as coats, unlike winter.

Here, for men in their 20s and 30s who want to wear summer clothes in style, we will introduce casual outfits that are conscious of trends, so please refer to them.

[Seasonal] Casual outfits that bring out the charm of men in their 20s and 30s

Before we focus on summer men's outfits, we will introduce seasonal casual outfits recommended for men in their 20s and 30s who are both young and mature.


The point of spring coordination is to incorporate spring-like colors and textures. For example, you should choose items such as yellow or light blue, or cool materials such as linen or cotton.

In spring when it's still chilly, a clean tailored jacket or cardigan is great. Tailored jackets are especially popular as standard items for adult men. The key is to choose light colors that are spring-like. Pair with casual denim pants for a neat and casual look.


Summer men's fashion tends to be overly simple outfits such as "T-shirt and pants" and "shirt and pants". Therefore, the point is to incorporate color into the outfit. For example, you can wear a simple white shirt and pants with a denim shirt, or incorporate an ash blue summer knit. Blue is a summery, refreshing color that makes it easy to aim for a good impression.


The point of autumn coordination is to incorporate autumn colors. It is a good idea to incorporate muted colors such as khaki, brown, and bordeaux into your outfit, so-called “autumn colors” that are familiar to adult men.

For example, if you combine a black setup with a terracotta knit, you can create a warm and autumnal outfit. A tailored jacket is a recommended item that is also active in autumn. By pairing it with a hoodie as an inner layer, you can create a moderately casual impression.


The point of winter coordination is to incorporate chic colors such as monotone and earth colors, and to use warm materials such as wool, cashmere, and tweed. Focus on outerwear, which is the first thing that catches your eye in your winter outfit, and dress it in style. Thick Chester coats and down jackets are essential items for men's winter fashion, and they keep you warm while enhancing your masculinity.

Winter tends to be dark overall, but if you incorporate warm colors such as terracotta and pink beige, you can create a warm winter outfit.

Let's take a closer look at the summer men's outfits. It seems that many people who usually wear work clothes such as suits are at a loss as to what to wear in private. In the summer, you tend to wear light clothes, so the repertoire tends to decrease, but the key to making your casual outfit look modern is to be conscious of freshness while incorporating trends.

elegant resort style

Many people think of vacations when they think of summer. Try a casual yet elegant style inspired by a vacation at a resort.

For example, it is recommended to put white somewhere in your coordination. People tend to avoid white because it makes them look fat and makes dirt stand out, but a navy denim shirt and white denim go well together.

marine style

When you think of summer, you think of the sea. Marine style is coordination that incorporates the designs and motifs of sailor uniforms. Borders and stripes, which are standard marine styles, can create a refreshing summer atmosphere, so it would be a good idea to incorporate them.

outdoor style

A style that incorporates items used in the outdoor scene into everyday life. It has gained popularity due to its high functionality and design, and has become a hot topic every year as a trend style.

Of course, there are many items that are conscious of outdoor use, and the popular point is that they are comfortable to wear even in summer, such as breathability and water absorption and quick drying. Items such as T-shirts, shorts, and caps are useful.

earth color

The style that incorporates earth colors that evoke images of nature such as the earth and plants is also popular. Incorporating a summer-like, breathable earth-colored hemp shirt or jacket will create a natural and calm casual outfit that will not make you feel hot or heavy.

Setup continues to be popular

The setup, which has been attracting attention as a trend in recent years, continues to be a popular item. For a set that has a neat image, choosing a brown color will give you a sense of familiarity and give you an image of a fashionable expert.

Fashion basics that you want to keep in mind with casual outfits

For men's casual outfits in their 20s and 30s, let's start with the basics of fashion.

Balance between clean and casual

There are two main types of clothes: neat and casual, and it is important to strike a balance between the two in order to create a mature atmosphere.

A T-shirt and denim pants will give you a too casual impression, but you can't create a casual impression with just a clean suit. For example, it is important to combine neat items with casual items, such as matching a knit with a jacket.

By setting the clean ratio to 50 to 80%, you can create a mature look.


The silhouette is also important for men's casual outfits. You can't create a mature look with a bulky size. It is important to be conscious of the overall silhouette and the size that fits the body moderately. Stick to the basic silhouette below.

  • I-line silhouette: Standard and smart impression
  • Y-line silhouette: Mature style looks good
  • A-line silhouette: Stable and masculine impression

color matching

Many people struggle with color matching, but it's actually not that difficult. The point is to use monotones of white, black, and gray, or limit the number of chromatic colors (other than white, black, and gray) to two based on monotones. This will reduce color matching failures.

Here are some examples of casual outfits recommended for people in their 20s and 30s.

Combine trendy items with marine style

The point of marine style, which is a summer iron plate coordination, is to casually incorporate colors and patterns. White, navy, and striped patterns are the basics, but recently, styles that combine trendy items such as shorts and sports sandals are popular.

By adding a striped pattern to the polo shirts and bottoms, you can enjoy a different and modern marine outfit.

Adult room in a relaxed silhouette

The relaxed silhouette is a style that incorporates loose items such as big silhouettes and linen materials to create a sense of looseness.

The trick is to limit the number of relaxing items you take in to two so that it doesn't get too rough. Incorporating loose items into the top will create a silhouette-conscious outfit.

Monotone coordination that emphasizes the ability to mix and match

A simple monotone outfit creates a cool and mature atmosphere. The charm of monotone coordination is that it can be worn for a long time regardless of the season, trend, or generation. We recommend a white polo shirt that gives a sense of neatness and cleanliness, or a style that combines a T-shirt with black skinny pants.

sophisticated sports mix

Sports mix literally means wearing items with a sports taste. The point to show a mature impression is to add sharpness to the taste of the items you combine. The royal road is to combine dressy items with sports-style items.

For example, if you combine a tailored jacket with jogger pants and sneakers, you will have a sharp look.

Items that create fashion with casual outfits for men in their 20s and 30s

The key to men's casual outfits in their 20s and 30s is to incorporate items with a mature impression. Here, we will introduce recommended items that bring out the charm of adults with a sense of neatness. Please use this as a reference when purchasing branded items online.

tailored jacket

Tailored jackets have a neat feel, and are outerwear that can create a mature atmosphere just by putting them on. You can easily create the charm of an adult man.


The Chester coat, which can be worn casually or neatly, is very mature. Choosing a calm color such as navy is the point to make it look chic.


The knit cardigan gives off a clean impression, but also gives it a moderately casual look. Easy to match with shirts and cut-and-sew items.

summer jacket

A summer jacket is useful for a neat outfit on a hot day. It is a convenient item that can be used regardless of whether you are on or off.

For men's casual wear in summer, we recommend remaking kimono fabrics for coordination.

People in their 20s and 30s are especially interested in fashion. Summer outfits are monotonous because you can't enjoy layering compared to winter. I would like to add variety to my wardrobe by choosing materials and shapes.
