Dress Code Guide for Men: Black Tie, Formal, Semi-Formal, and What to Wear

Understanding what to wear for each level of dress code isn’t just about etiquette—it’s about showing up prepared, polished, and confident. 

If you’ve ever stared at a vague event invitation wondering whether to grab a tux or a navy suit, this guide eliminates the guesswork. Here’s what each dress code actually means and how to execute it flawlessly.

Black Tie Dress Code: What It Means and What to Wear

Black tie is the most common high-formality code you will see on wedding or gala invites. It’s evening wear that signals elegance without being as rigid as white tie.

What to Wear

  • Tuxedo jacket (black or midnight blue)
  • Tuxedo trousers with satin stripe
  • White dress shirt with a pleated or pique front
  • Black bow tie (never a necktie)
  • Black patent leather or high-shine oxfords
  • Optional: cummerbund or low-profile waistcoat

Do not: Show up in a regular suit, wear sneakers, or skip the bow tie. If the invite says “black tie optional,” default to a tuxedo unless you know the event leans more relaxed.

Pro Tip: If you don’t own a tux, invest in a tailored one now—you’ll need it more often than you think. ATL Tailor can create a custom tuxedo in just seven days.

Formal Dress Code for Men: How It Differs from Black Tie

Formal can be a confusing label. It often falls just below black tie in formality and can include dark suits, especially for daytime or business-related events. Evening “formal” events, however, often expect tuxedos.

What to Wear (Daytime Formal)

  • Dark navy or charcoal suit
  • Crisp white or pale blue dress shirt
  • Conservative silk tie
  • Leather oxford or derby shoes

What to Wear (Evening Formal)

  • Tuxedo (same as black tie)
  • Or black/dark suit with elevated styling and textures

Watch Out For: Some hosts use “formal” when they really mean black tie. If you’re not sure, ask. Or play it safe with a tux.

Semi-Formal Attire for Men: Sharp But Not Stiff

Semi-formal is a notch down from formal. Think: weddings, evening business events, upscale dinners. It’s still dressy, but more flexible and contemporary.

What to Wear

  • Tailored suit in navy, gray, or seasonal fabric
  • Dress shirt in solid or subtle pattern
  • Tie optional (but often preferred)
  • Leather dress shoes or loafers
  • Pocket square to elevate the look

Avoid: Casual suits, wrinkled shirts, or sneakers. It’s not cocktail attire, and it’s definitely not business casual.

Black Tie Optional, Cocktail, and Other Variants

These hybrid dress codes confuse everyone. Here’s how to handle the most common ones:

Black Tie Optional

  • Tuxedo is best, but a dark suit with formal accessories (white shirt, black shoes, elegant tie) can pass

Cocktail Attire

  • Slim suit, shirt, and tie in playful colors or patterns
  • Stylish footwear (double monk straps, sleek loafers)
  • More room for personality, but still polished

Creative Formal / Gala Themes

  • Anchor the outfit in classic formality
  • Add texture, color, or accessories aligned with the event theme

Common Questions About Men’s Dress Codes

Can I wear a navy suit to a black tie event?

No. A navy suit is appropriate for semi-formal or business formal, but not for black tie. Black tie means tuxedo.

Is a tuxedo required for black tie optional?

Technically no, but it’s the best choice. If not, wear your darkest, sharpest suit with formal accessories.

What does formal dress code mean for men?

Usually a tuxedo for evening events or a dark suit with a tie for daytime. When in doubt, lean formal.

What is semi-formal for men?

A classic suit and shirt combination, with or without a tie. Polished but not as rigid as formal wear.

How to dress for a gala?

Tuxedo is safest. For themed galas, you can build on a tux base with elevated details or color, depending on the theme.
