Style Guide & Suit Etiquette

Dressing with Purpose

A suit is not just clothing. It is a language, a code, and sometimes even a tradition. The way you wear a suit can determine how you are perceived, how you feel, and how you carry yourself. In boardrooms, weddings, galas, and even casual gatherings, the right choice of suit sends a message before you say a word.

That is why we created our Style Guide & Suit Etiquette: a comprehensive journey into the world of formalwear. It is here to answer not just what suit to wear, but also when, how, and why.

Tuxedos – The Pinnacle of Formalwear

When the invitation says black tie, there is only one correct response: the tuxedo.

  • When to Wear: Galas, operas, red carpet events, black-tie weddings, and exclusive evening functions.

  • Style Notes: Tuxedos are defined by satin or grosgrain lapels, side-striped trousers, and typically a bow tie. They are almost always worn after 6 p.m.

  • Why It Matters: A tuxedo is not just formal; it is ceremonial. It tells the world you respect the occasion and embrace its elegance.

A man who owns a tuxedo owns a timeless ticket to the world’s most formal occasions.

2-Piece Suits – Versatile, Essential, Everyday Elegance

The 2-piece suit—consisting of a jacket and trousers—is the backbone of a modern wardrobe.

  • When to Wear: Business meetings, daily office wear, job interviews, dinner dates, and semi-formal gatherings.

  • Style Notes: Works across fabric types and fits, making it the most flexible option. Easy to dress up with a tie or down with an open collar.

  • Why It Matters: The 2-piece is the suit of versatility. Every man needs one, if not several, for daily life.

It is the universal language of tailoring: simple, direct, and endlessly adaptable.

3-Piece Suits – Power, Tradition, and Timeless Authority

A 3-piece suit adds a waistcoat to the 2-piece ensemble, elevating formality and presence.

  • When to Wear: Weddings (both guest and groom), high-level business meetings, formal presentations, and events where you want to stand out.

  • Style Notes: The waistcoat adds structure, sharpens posture, and creates a polished silhouette. Often chosen for celebratory occasions.

  • Why It Matters: A 3-piece suit signals power, sophistication, and tradition. It is less common, making it memorable.

For weddings, nothing rivals the elegance of a well-tailored 3-piece—it balances tradition with impact.

Weddings vs. Business – The Etiquette Divide

Weddings

A wedding is both formal and celebratory, which makes etiquette crucial.

  • Groom: 3-piece suit or tuxedo depending on formality.

  • Guests: 2-piece suits in neutral or seasonal colors (navy, charcoal, grey in winter; lighter shades or linen in summer).

  • Black Tie Weddings: Tuxedos only—no exceptions.

Business

Business attire is about authority and respect without overshadowing.

  • Daily Business: 2-piece suits in subtle colors (navy, charcoal, grey).

  • Boardrooms / High-Level Meetings: Dark 2-piece or 3-piece, conservative ties, polished shoes.

  • Business Casual: 2-piece without tie, or mix-and-match blazer and trousers.

Where weddings invite celebration, business suits demand discipline.

Occasion-Based Suit Etiquette

  • Job Interview → A navy or charcoal 2-piece, simple tie, polished shoes. Neutral, professional, confident.

  • Dinner Party → Slim-fit 2-piece, open collar shirt, no tie. Smart but approachable.

  • Formal Wedding → 3-piece or tuxedo, depending on dress code. The groom may add a boutonnière.

  • Summer Garden Party → Linen or cotton suit, light colors (beige, sand, sky blue). Relaxed but refined.

  • Evening Gala → Black tuxedo, white dress shirt, black bow tie, polished shoes.

Every occasion has its code. Knowing it is the difference between dressing well and dressing right.

Key Details of Suit Etiquette

  • Buttons: Always leave the bottom button of a suit jacket undone. For 3-piece, the waistcoat bottom button also stays open.

  • Ties: A business tie should cover the waistband. At black-tie events, bow ties are non-negotiable.

  • Shoes: Black Oxford shoes for tuxedos; brown or black leather for suits depending on fabric color.

  • Accessories: Less is more—pocket squares, cufflinks, and watches should enhance, not overwhelm.

Etiquette is not about restriction—it is about respect.

Seasonal Suit Etiquette

  • Summer: Linen and cotton suits, lighter shades, unlined jackets.

  • Winter: Flannel wool, tweed, or velvet. Darker, richer tones.

  • Transitional Seasons: Lightweight wool blends, versatile greys and blues.

Dressing with the season is part of etiquette—it shows awareness and refinement.
