How to Wear a Suit - Complete Guide

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.

1. Buttoning all buttons: Betrays a total ignorance of the codes. 2. Short socks: Showing calves when seated = careless. 3. Tie too short/long: Should touch the belt exactly. 4. Pocket square matching the tie: Same fabric = a dated 1980s faux pas. 5. Brown shoes with a black suit: An inadmissible warm/cool clash. 6. Jacket too long/short: Should cover the seat, no more. 7. Excessive trouser break: A maximum of 1-2cm break on the shoe. 8. Wearing a tie without a pocket square: An imbalance (formal above, empty pocket below). 9. Undershirt visible with an open collar: Wear a V-neck undershirt that stays hidden. 10. Mixing metals: Silver AND gold together = inconsistent. 11. Jacket sleeves too long: No shirt showing = sleeve too long. 12. Braces AND belt: Never both - choose one. 13. Creased/dirty suit: An impression of carelessness negates any quality. 14. Jacket too tight: Buttons pulling, X-shaped creases in the back = too small. 15. Wearing a tuxedo during the day: Tuxedo = after 6pm only. These mistakes mark you as a beginner. Connoisseurs notice ALL of them.

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.
