Dress codes incite fear into the hearts of the men. But gents, contrary to this sense of doom, they aren't there to restrict you. Instead, they exist to show respect for the occasion and create visual harmony and, once known, actually take away any feeling of ‘what should I wear’.
With our easy-to-follow guide, you'll no longer worry about whether you're over- or under-dressed, fitting smoothly into any formal event with the confidence that turns heads.
What Does Formal Attire Mean for Men?
Formal attire is a tiered dress code system dictating exactly how ‘dressed up’ you should be for an event. White tie sits at the most formal end, with business formal and cocktail generally being the least formal of the bunch.
While the particular pieces vary (tuxedo to suit), the overarching principle remains; read the invite and match the formality.
When is Formal Attire Required?
Generally speaking, you'll come across formal dress codes where an event comes with an invitation. That invitation will invariably state the required dresscode, such as:
Weddings
Formal wedding dress codes change with the time of day, venue, and the couple's personal taste.
Guests should:
-
use the time and venue to guide your outfit.
-
not upstage the wedding party.
-
Match the formality or stated outfits on the invite (morning dress, black tie etc)
Black Tie Events
Black tie has its own unique rule set. We're putting it in black and white to demystify the code:
-
Follow the black tie dress code (explained below)
-
Keep your jacket on during the meal.
White Tie Events
While rare for the average person in modern day, white tie events remain the pinnacle of formal and traditional social occasions. Think state dinners, elite award galas, and royal gatherings. You're expected to adhere to full evening dress: black evening tailcoat, black trousers with a satin side stripe, white wing-collared shirt, a white waistcoat and bow tie.
Award Ceremonies
Red carpet events and similar award ceremonies often come with the black tie formal dress code. However, take note of the specific occasion and dress accordingly, they don't all fit the same mould.
Formal Dinners & Galas
Depending on the event's standard, most formal dinners and galas boast a black tie or black tie optional dress code. However, some royal-led or attended events will dictate white tie dress. If the dress code is optional, we absolutely suggest following it. You can never be overdressed, but you can easily be underdressed.
Corporate Events
At business events, it's less about flair and more about professionalism. Consider it your chance to communicate reliability with nothing but your attire.
When dressing for corporate gatherings, it's vital to know your industry's norms. Tech tends to be more relaxed, whereas finance and law sectors lean traditional.
The Essential Elements of Men's Formal Attire
Yes, the pieces change depending on the specific formal dress code. However, there are a few key elements that you don't want to miss, regardless of specifics.
The Suit or Tuxedo
Tuxedos, dinner suits, three-piece suits, and two-piece suits fit different varieties of formal dress. However, the former is favoured at many events, particularly when "black tie optional" or "black tie preferred" sits on the invite.
Regardless of the suit or tux, getting the foundation right is essential:
-
Cut: Single-breasted in the most versatile option in the formal category. Although, double-breasted are on trend in 2026. Leave the bottom button open on your double breasted jacket.
-
Fabric: For the best drape, durability, and flexibility balance, choose wool and wool blends. Linen and tropical wool for summer; heavier flannels and wools for winter.
-
Fit: Ensure the shoulders sit on your natural line, ie the shoulder seam is in line with the end of your shoulder. You’ll want the sleeves revealing roughly ¼-inch of shirt cuff. A ‘sliver’ if you will.
Dress Shirt
Always choose a white shirt for black and white tie, saving light blue for business formal and soft colours/subtle patterns for cocktail parties.
As for the fit, the sleeves should end at the base of your thumb, and it should never bunch up beneath your jacket. If you can slide one finger around the inside of the collar, you've hit the nail on the head.
Formal Trousers
The trousers should match the fabric and colour of your suit. Ideally, opt for a pristine line down the centre of the leg, ensuring they break softly at the shoe. In tailoring, a break refers to the fold created where the trouser impacts the shoe. Breaks are a personal choice. No break means the trousers just brushes the shoe. A single break = a single fold/crease. A double break = two folds. Anything more and those trousers are too long my friend.
Dress Shoes
Popular dress shoe options for formal events include:
-
Patent leather Oxfords
-
Calfskin Oxfords
-
Polished loafers
Opera pumps are traditional for white tie occasions, but they're rarely seen in today's world.
Regardless of the style, ensure your shoes are extremely polished. Stick to black for black tie and white tie, and leave dark brown shoes at home until you attend a business formal gathering.
Tie or Bow Tie
Bow ties are required for tuxedos. Ideally crafted from the same material as your tux's lapel facing. That means the same colour as well.
Ties for all other events are a fun way to inject some colour and personal style. Just keep the patterns conservative if you're attending a business event, and always ensure the tip hits the top of your trousers.
Pocket Square
When wearing a tuxedo, most men choose a white pocket square. Note that Frank Sinatra opted for an orange pocket square. Just be sure to know the rule before you break it. For dinner and other suits, ensure it complements your tie but doesn't match exactly.
Belt or Braces
Tuxedo trousers will have a side adjuster instead of belt loops. However, suspenders are the traditional choice for tuxedos if extra support is required. If the trousers have a belt loop then it's up to you whether to don a belt or braces. Some say ‘if there are belt loops, use them,’ whereas others will say if a pair of trousers fit well, you don’t need a belt.
Watch & Accessories
Remove your sports watch and choose a thin, quiet watch instead. Don't be afraid to add cufflinks or studs for formal shirts and a waistcoat for traditional black tie.
Formal Dress Codes Explained
Remember "formal" is a tiered system. While some invitations may state "formal" alone, it's unlikely. Typically, you'll be met with one of the previously mentioned dress codes from the formal spectrum. Broken down below:
White Tie
It's the most formal dress code in menswear, leaving no room for personal interpretation.
You're expected to wear:
-
A black tailcoat with silk-faced lapels
-
Matching black dress trousers with a silk side stripe
-
Stiff-front white dress shirt with wing collar
-
White bow tie
-
White waistcoat
-
Highly polished Oxfords/black patent leather court shoes
For ultra-formal state events, you can don white gloves.
Black Tie
While not as formal as white tie, black tie still requires correctness. It is a descendant of the white tie outfit after all. Its elegance comes from rule-following, not creativity.
You're expected to wear:
-
A black or midnight blue tuxedo
-
Matching trousers
-
White dress shirt with turndown or wing collar
-
Black bow tie
-
Highly polished lace-up or black patent leather shoes
-
Pocket square
-
A waist covering (cummerbund or waistcoat)
Black Tie Optional
This is perhaps the most misunderstood dress code, but it's simple once you know… it is simply a black tie event where a two- or three-piece suit is accepted as a tuxedo alternative. That said, if you have, or have access to, a tuxedo then we strongly recommend that you follow the traditional dress code rules.
If you don't want to wear standard black tie dress, you can don:
-
Black, dark charcoal, or navy suit
-
White/ivory shirt
-
Plain, dark-coloured silk tie
-
Black Oxfords
Business Formal
Business formal is all about looking professional and sharp.
You're expected to wear:
-
A dark suit
-
Light-coloured dress shirt
-
Solid-coloured tie
-
High-quality leather belt (optional)
-
Black/dark brown polished leather Oxfords
Cocktail Attire
This sits at the party end of the formal dress code. It offers a more social, creative vibe, yet exudes effortless tailoring.
Choose:
-
A solid colour suit, with the exact colour depending on the season
-
A crisp shirt in white, ivory, or pale blue
-
Oxfords, loafers, or Derbies in leather or suede
-
A more expressive tie (optional)
Suit VS Tuxedo: What's the Difference?
The tuxedo and the suit are closely related, but the former features satin detailing on the buttons, lapels, and trouser seams, while the latter boasts matching fabric throughout to suit a variety of occasions.
Best Colours for Formal Attire
Choosing the colour of your formal ensemble runs deeper than selecting your preferred shade, it's about making the right impression. Depending on the event, some hues are better than others:
-
Black: This classic choice is the ultimate formal colour. It provides a refined, polished look.
-
Navy blue: Known for its versatility and ability to flatter all skin tones, navy blue is ideal for corporate events, business meetings, and semi-formal occasions.
-
Charcoal grey: It offers a serious, professional aesthetic without the harshness sometimes exuded by classic black. It pairs well with different shirt colours, ensuring flexibility for business formals, interviews, and weddings.
-
Light grey: For a contemporary vibe, light grey works wonders. It's a go-to choice for daytime events and summer weddings.
-
Burgundy: This option gives richness and depth to your formal attire. It makes a statement without being overly loud.
-
White/Ivory: Perfect for fashion-forward events, summer galas, and destination weddings, white/ivory suits may be hard to maintain, but they stand out gorgeously.
-
Midnight blue: Lots of high-end tuxedos come in midnight blue for a unique yet formal appearance at luxury dinners and black tie events.

Once you've arrived at your formal event, it's too late to undo many typical mistakes. By understanding these common pitfalls beforehand, you avoid having to learn the hard (sometimes embarrassing) way:
-
Wearing an oversized or undersized suit

Wearing a tuxedo without a bow tie
