Men’s Dress Code Explained: Guide

Black Tie is a formal evening dress. Elegant evening wear. Correctness matters, there is no room for creativity.

What to wear

• Black or midnight blue dinner jacket with silk lapels (peak or shawl)
• Matching trousers with a single silk stripe; the silk stripe is not compulsory
• White dress shirt with a turndown or (less commonly now) wing collar
• Black silk bow tie (self‑tie)
• Black patent leather or highly polished lace‑up shoes
• Optional: cummerbund or low-cut waistcoat, white pocket square, discreet cufflinks

Avoid wearing

• Normal business suits masquerading as Black Tie
• Ties
• Brown shoes, casual loafers or plain Derby shoes

Black Tie Optional is one of the most misunderstood dress codes. A Black Tie event where a dark formal suit is accepted as an alternative to a tuxedo.

Option – Black Tie:

• Standard Black Tie as above

Acceptable alternative – dark suit:

• Dark navy, dark charcoal or black suit
• White or ivory shirt
• Dark, plain silk tie (black, deep navy, burgundy, very subtle texture)
• Black or dark brown leather Oxfords

Avoid wearing:

• Wearing a black bow tie with a normal suit – it looks like an imitation tuxedo
• Light colour or flashy suits
• Suede shoes - they are too casual
• Don’t heavily accessorize: a simple watch and pocket square is plenty

“Formal” is usually used loosely, but in traditional etiquette, it generally aligns with Black Tie in the evening, or a very dark suit when Black Tie is impractical.

What it usually means:

• Evening: Black Tie or a dark, conservative suit and tie
• Daytime: dark lounge suit (and in very traditional British contexts, morning dress for weddings and major occasions)

What to wear:

• Dark navy or charcoal two‑piece suit
• White or light blue shirt
• Conservative silk tie
• Black or dark brown Oxfords

Avoid wearing:

• Casual items like jeans, t-shirts, sneakers, shorts, and cotton fabrics
• Anything too revealing, ill-fitting, or overly bright/patterned

Semi‑formal sits below Black Tie and above Smart Casual. It is often used for weddings and evening events that are not Black Tie.

What it means

A suit is expected, not a tuxedo.

What to wear

• Two‑piece suit – darker for evening, lighter tones acceptable for daytime
• Dress shirt (plain or with subtle pattern)
• Tie usually expected, especially in the evening
• Leather dress shoes – Oxfords, Derbies or brogues

Avoid wearing

• Jeans, trainers, casual boots
• Busy patterns or flashy accessories – semi‑formal is reserved in its essence

Cocktail attire is the “party” end of semi‑formal – sharper and more social, but still tailored.

What it means

A suit with more personality.

What to wear

• Solid colour suit. Choose darker colours for autumn/winter: navy, charcoal, dark green, dark brown. Lighter in spring/summer
• Crisp shirt – white,ivory, pale blue

• Shoes – Oxfords, Derbies, loafers. Can be leather or suede.

Avoid wearing

• Anything that looks like night-out clubwear
• Overly shiny fabrics
• Sneakers.

Dressy casual lies in the space between conventional, casual, and festive vibes. It relies on thoughtful combinations rather than strict rules, bringing together striking pieces and more comfortable elements.

Casual pieces upgraded through tailored cut, elevated fabrics, well coordinated accessories.

• T shirts
• Sneakers
