Start Here: 3 Basics of men’s formal attire for a Refined Look

The basics of dressing for formal occasions are suit selection, silhouette, and cleanliness. Paying attention to these three points alone can greatly change the impression you make.

Choose a Suit Suitable for Formal Occasions

For formal occasions, deep dark navy and charcoal gray are recommended. These versatile colors convey trust and professionalism, making them suitable for a wide range of settings from business to ceremonies.

When in doubt, navy should be your first choice, followed by charcoal gray. At weddings, the appropriate attire may vary depending on your role, such as whether you are a guest of honor or a general guest, as well as the style of the ceremony. However, in most cases, dark navy or charcoal gray is a reliable choice.

A two-piece suit with a jacket and pants is the basic option, but if you want to increase the level of formality, a three-piece suit with a vest is also worth considering. For the fabric, choose an all-season wool blend with structure and an elegant sheen to create a refined impression.

Refine the Silhouette

No matter how expensive the suit is, it will not look good if the size does not fit properly.

Use the following checklist to choose a suit that follows your body shape.

Shoulders: The shoulder seam sits directly above the edge of your shoulder bone

Chest: There is enough room for one fist when the button is fastened

Pay Attention to a Clean Look

Even if the size is right, maintenance like removing wrinkles, pilling, or cleaning shoes is essential to men’s formal attire, as neglect can immediately lower your overall impression. Make it a habit to check the following points before going out.

  • Brush off dust, lint, and hair
  • Use steam to smooth wrinkles on the jacket and pants
  • Check the collar and cuffs of your shirt for stains
  • Polish your leather shoes by the day before

Stand Out Through the Details: Item-by-Item Styling Tips for men’s formal attire

Once you have mastered the basics, the next important step is to follow the rules for each item carefully. Paying attention to the details helps create a more polished impression.

How to Wear the Jacket

The basic rule for jackets is proper button etiquette.

The bottom button is decorative, so it should not be fastened. For a two-button jacket, fasten only the top button. For a three-button jacket, fasten the middle button, or the top and middle buttons.

When sitting down, unfasten all the buttons to prevent the jacket from losing its shape or damaging the fabric. When standing up, fastening the button again with a natural motion is considered a smart gesture.

How to Wear the Shirt

For formal occasions, a plain white shirt is a good choice because it creates a clean and sincere impression.

A regular collar or semi-wide collar is versatile and easy to style.

For a well-balanced look, adjust the sleeve length so that about 1 to 1.5 cm of the shirt cuff shows from the jacket sleeve. Around the neck, aim for about 2 to 3 cm of room.

How to Wear the Tie

The tie is an important item that adjusts the impression of men’s formal attire.

The basic rule is to adjust the length so that the tip just touches the top of the belt buckle. If it is too long or too short, it can look untidy.

How to Wear the Tie

Choose basic colors such as navy, burgundy, or gray, and go for understated patterns such as small motifs or regimental stripes for a refined impression. Coordinating the colors of your shirt, jacket, and tie also helps create a unified look.

How to Wear the Pants

For pants length,

a half break that lightly touches the top of the shoes is recommended. Compared with a one-break length, where one fold appears at the hem, a half break creates a cleaner impression.

For socks, choose dark-colored mid-calf socks that cover your calves so your bare shins do not show when you sit down or cross your legs. White socks and short socks are strictly inappropriate for formal attire for men.

How to Use Pockets Properly


Proper pocket use is an often-overlooked detail that can significantly elevate the standard of your men’s formal attire.

The breast pocket is reserved for a pocket square. Putting pens, smartphones, or wallets in it is considered poor etiquette. Items placed in the waist pockets or pants pockets can also disrupt the silhouette, so as a general rule, pockets should be kept empty in formal settings. Store business card cases and slim wallets in the inside pocket of your jacket.

How to Match Leather Accessories

In suit styling, matching the color of your leather shoes and belt is a basic rule. Coordinating your watch’s leather strap and bag in the same color family will make the outfit look even more refined.

Suit Color Recommended Leather Shoe Color Impression
Navy Black,Dark brown Black for a formal look, brown for a softer impression
Charcoal gray Black A reliable and formal impression
Black Black A sleek, polished impression

For shoes, black cap-toe oxfords are the basic choice. Avoid flashy sneakers or sandals.

Frequently Asked Questions

Below are answers to common questions regarding the nuances of men’s formal attire to help you make the best choices for your next event.


Q. Should I avoid a black suit for formal wedding attire?

A. Not necessarily. A black suit is a classic formal style that can be worn to weddings. However, if you coordinate everything in black, it may create a stronger impression of mourning attire. Pair it with a white shirt, a silver, light gray, or softly colored tie, and add a pocket square for a more celebratory look. Recently, dark navy and charcoal gray have also become popular choices because they look elegant without feeling too heavy.


Q. Do I always need to wear a pocket square?

A. It is not a breach of manners to go without one, but adding a pocket square raises the level of formality. Match it with the color of your shirt or tie, while avoiding an exact match in pattern, for a refined look.


Q. Can I wear the same suit for business and weddings?

A. A plain dark navy suit is easy to use for both. For weddings, you can add a festive touch with your shirt, tie, and pocket square. For business, switch to more understated accessories to adapt the same suit to the occasion.
