How to Wear a Suit - Complete Guide

1-BUTTON JACKET

Always buttoned when standing. Unbuttoned when seated. (Rare - tuxedos, some double-breasted styles).

2-BUTTON JACKET

Fasten the TOP button only. The bottom is always undone. Unbutton when seated. The most common style.

3-BUTTON JACKET

'Sometimes, Always, Never' rule. Top button = optional (sometimes). Middle button = always. Bottom button = never. OR fasten only the middle. Unbutton when seated.

DOUBLE-BREASTED JACKET

All buttons closed at all times, EVEN WHEN SEATED. The double-breasted suit loses its structure if unbuttoned. Exception: very relaxed settings.

WAISTCOAT

The bottom button of the waistcoat is ALWAYS undone. This tradition dates back to Edward VII (too corpulent to fasten the bottom). The custom has been maintained ever since.

WHY UNBUTTON WHEN SEATED

A buttoned jacket pulls and creates unsightly creases when you sit. Unbuttoning preserves the jacket's shape and your comfort. Re-button when you stand.

FATAL ERROR

Buttoning all buttons = a beginner's mistake that betrays ignorance of the codes. Connoisseurs spot it immediately.

GENERAL RULE

A maximum of 3 colours across the complete outfit (suit + shirt + tie + pocket square + shoes). Beyond that = visual overload.

NAVY SUIT

White shirt (classic), pale blue (modern), pale pink (creative). Burgundy, grey, dark navy or gold tie. Black shoes (formal) or dark brown (casual). White pocket square (understated) or burgundy (festive).

GREY SUIT

White shirt (standard), pink, pale blue. Pink, burgundy, navy or lilac tie. Brown shoes (cognac, chocolate) recommended. Pocket square coordinated by colour with the tie.

BROWN/BEIGE SUIT

White or sky blue shirt. Navy, olive green, burgundy or dark brown tie. Brown shoes COMPULSORY (tan, cognac). NEVER black with a warm-toned suit. Natural linen or coordinated pocket square.

CONTRAST RULE

The tie should be darker than the shirt, lighter than the suit. This creates a harmonious top-to-bottom gradation.

MONOCHROME

Suit, shirt and tie in the same colour family (navy + sky blue + dark navy) = sophisticated elegance. Requires mastery of tonal nuance.

PLAIN SHIRT + PATTERNED TIE

White or plain shirt with a patterned tie (stripes, dots, prints). A safe, elegant combination. The most common.

STRIPED SHIRT + PLAIN TIE

Fine-striped shirt with a solid tie. Visual balance. Ideally the tie picks up one of the stripe colours.

AVOID

Striped shirt + striped tie = pattern clash. Checked shirt + geometric-patterned tie = overload.

PROPORTIONATE KNOT

Tie knot width proportionate to the shirt collar width. Wide collar = wide Windsor knot. Narrow collar = four-in-hand.

TIE LENGTH

The tip of the tie touches the belt buckle. Neither higher (looks odd) nor lower (looks careless). The narrow blade must never extend beyond the wide blade.

POCKET SQUARE NEVER MATCHED

The pocket square is COORDINATED by colour with the tie but NEVER in the same fabric/pattern. Matched = an 1980s faux pas. Coordinated = elegance.

WITHOUT A TIE

An open collar is acceptable in smart casual. Unfasten 1 or 2 buttons (never 3+). Avoid an undershirt showing. Remove the pocket square if no tie is worn (creates an imbalance).

METAL RULE

Belt buckle + shoe buckles + watch + cufflinks in the same metal (silver OR gold, no mixing).

LEATHER PAIRING

Belt and shoes in the same leather colour. Black shoes = black belt. Brown shoes = brown belt. Exception: two-tone shoes.

SHOES BY SUIT

Black/charcoal suit = black shoes. Dark navy = black or dark brown. Medium grey/blue = cognac brown. Beige/brown = light brown.

SOCKS

ALWAYS calf-length minimum. NEVER short socks that expose the calf when seated. Sock colour = tone-on-tone with trousers OR shoes. Or a discreet tie-coordinated accent.

PATTERNED SOCKS

Acceptable in creative settings. Discreet patterns. Avoid loud colours in strict corporate contexts. Socks are a subtle touch of personality.

BRACES

Braces OR belt, NEVER both at the same time. Braces = traditional elegance. If the jacket is removed, braces should be understated.

POCKET SQUARE COMPULSORY

For any formal or semi-formal outfit, a pocket square is NOT optional. An empty pocket = an unfinished outfit. White linen pocket square = the safe universal choice.

WATCH

A single watch, on the left wrist (for right-handers). Watch style consistent with the suit's formality. Tuxedo = understated dress watch. Business casual = sport watch acceptable. Avoid coloured plastic watches with a suit.

MEN'S JEWELLERY

A wedding ring is acceptable. A signet ring is optional (right hand, little finger). Avoid: multiple bracelets, visible necklaces, earrings in corporate settings. Restraint always.

BELT VS BRACES

Never both. Braces are more elegant, a belt more practical. With a tuxedo = braces are compulsory.

OVERCOAT COORDINATION

An overcoat in the same tone or darker than the suit. Charcoal or navy works with 90% of suits. Buttoned outdoors, removed indoors.

BAG/BRIEFCASE

Quality leather, understated. Colour coordinated with shoes. Avoid backpacks with a formal suit (strict corporate). A classic leather briefcase or leather messenger bag.

VISUAL DETAILS

1-1.5cm of shirt showing below the jacket sleeves. Pocket square showing 1-2cm from the pocket. Tie touching the belt. These details create visible elegance.

Dress codes are a source of confusion because their terms vary across countries and eras. Here is a guide to the main dress codes to ensure you never get it wrong.

BLACK TIE

Black or midnight blue tuxedo, compulsory. White bib-front shirt, black silk bow tie, black patent Oxfords. No tie, no standard suit. A cummerbund or waistcoat is optional.

CREATIVE BLACK TIE

Classic tuxedo but with freedom for the bow tie (velvet, patterned) and a coloured pocket square.

WHITE TIE

Tailcoat, white pique waistcoat, white bow tie, stiff-fronted shirt. The most formal, reserved for state galas.

BUSINESS FORMAL

Dark suit (navy, charcoal), white or pale blue shirt, restrained tie, Oxfords. For interviews, presentations, important meetings.

BUSINESS CASUAL

Suit or blazer with chinos. Open collar acceptable. No tie required. Well-kept shoes but more freedom (loafers, Derbies).

SMART CASUAL

No full suit required. Blazer, V-neck jumper, chinos, loafers or premium trainers. Relaxed but polished elegance.

The same suit does not suit every season or every occasion. Adapting the choice of fabric, colour and style to the context demonstrates a complete mastery of dress codes.

SUMMER

Lightweight, breathable fabrics - linen, cotton, tropical wool fresco. Lighter colours acceptable (beige, light grey, sky blue). Unstructured construction for lightness. Loafers without socks in very casual contexts only.

WINTER

Flannel, tweed, heavier wool. Dark, rich colours (navy, charcoal, burgundy). A waistcoat added for warmth and style. Chelsea boots or chukka boots acceptable.

MID-SEASON

Medium-weight wool, crepe. Maximum versatility. Spring-autumn suits form the core of the wardrobe.

WEDDING

Light suit in summer (light grey, blue), dark in winter. Avoid black unless it is an evening ceremony. Pocket square and boutonniere are customary.

FUNERAL

Black or dark charcoal suit, white shirt, black tie. Absolute restraint. No coloured pocket square.

DAILY OFFICE

Rotate a minimum of 3-5 suits to avoid wear. Alternate colours and textures across the week.
