What to Wear to a Military Ball: Men's Style Guide

A military ball is one of the most formal nights on the calendar, held to honor a branch's history and traditions. Service members wear their formal dress uniform, while civilian guests dress to match that level of formality. Here is a clear guide to what to wear to a military ball as a civilian man, from the tuxedo down to the etiquette, with an easy way to rent the whole look.

Here's what this guide walks through, step by step:

• Understanding the military ball dress code
• What civilian men wear
• Accessories and etiquette
• How to rent your look

Understanding the Military Ball Dress Code

A military ball sits at the formal end of the scale, on par with a black-tie event.

A Black-Tie Level Event

The formality is the key thing to grasp.

• Service members wear their formal dress uniform, with medals and insignia
• Civilian men dress to the black-tie standard that matches
• The focus of the night stays on the service member in uniform

Check the Invitation First

A little homework removes the guesswork.

• The invitation usually spells out the required attire
• Ask your service member what their unit expects
• Note any theme, and keep your attire within it

What Civilian Men Wear

Civilian guests have two solid options, and both read sharp at a ball.

A Tuxedo, the Classic Choice

The tuxedo is the civilian match for a dress uniform.

• A black or midnight-blue tuxedo with satin lapels
• A crisp white shirt and a black bow tie
• A cummerbund or vest, and black patent leather shoes

Our guide on ​how to dress for a black-tie event covers the details.

A Dark Formal Suit, the Flexible Choice

A dark suit is common and welcome, as long as it stays formal.

• A well-fitted suit in black, charcoal, or navy
• A white dress shirt with a tie or bow tie
• Polished black leather shoes

For the line between codes, see ​the black-tie optional dress code for men.

Tuxedo vs. Dark Formal Suit

Formality

• Tuxedo: The closest civilian match to a uniform
• Dark Formal Suit: Formal and widely accepted

Jacket

• Dark Formal Suit: Standard matching lapels

Neckwear

Accessories and Etiquette

The finishing touches and a little etiquette carry a lot of weight at a ball.

The Finishing Touches

Keep the details clean and coordinated.

• Cufflinks and a pocket square in complementary tones
• A slim dress watch on a leather strap
• Comfortable dress shoes, since the night includes dancing

Dress-Code Do's and Don'ts

A few simple guidelines keep you on point.

• Do keep colors dark and the look classic

Frequently Asked Questions

What do civilian men wear to a military ball?

Civilian men wear a tuxedo or a dark formal suit. A tuxedo is the closest civilian match to a dress uniform, but a well-fitted suit in black, charcoal, or navy with a tie or bow tie is common and welcome. Check the invitation for the exact dress code.

Can you wear a suit instead of a tuxedo to a military ball?

Yes. A dark, formal suit in black, charcoal, or navy is a common and accepted choice, paired with a white shirt and a tie or bow tie. Make sure it is a full suit rather than a sport coat, and keep the shoes polished and black.

How formal is a military ball?

A military ball is highly formal, on par with a black-tie event. Service members wear their formal dress uniforms, and civilian guests are expected to match that level. That means a tuxedo or a dark formal suit for men, and a full-length gown or formal outfit for women.

What color suit should you wear to a military ball?

Stick to dark, classic colors: black, charcoal, or navy. These read formal and keep the focus where it belongs, on the service members in uniform. A small accent that nods to the branch's colors is a nice touch, but keep the suit itself understated.

What accessories go with military ball attire?

Keep them refined and coordinated: cufflinks, a pocket square, and a slim dress watch. Black patent or polished leather shoes finish the look. Since the night involves dancing and lasts for hours, choose comfortable, well-fitting shoes you can wear all evening.

How far in advance should you rent a tuxedo for a military ball?

Give yourself a few weeks, so there is time to confirm the fit. Generation Tux delivers each rental 14 days before the event, with free replacements, so you can try everything on and swap a piece if needed well before the ball.
