What To Wear To A Formal Business Conference: Men’s Edition

January 17, 2025

You’re prepping for a formal business conference.

The stakes? 
Networking, making a positive first impression, and nailing every interaction.

Your outfit?
It’s more than just clothes. It’s your personal brand, your silent business card. Packing smart and dressing sharp guarantees you look the part, no matter where your business trip takes you.

So, how do you take the stress out of figuring out what to wear to a formal business conference? By focusing on versatile pieces that maximize your wardrobe’s functionality. What does that mean? It means packing pieces that can easily transition from a networking brunch to a keynote to a night out with new connections. With tips from Next Level Wardrobe’s professional stylists, you can seamlessly go from men’s business formal to power casual.

(Plus, it’ll free up space in your luggage and simplify your packing.)

Fellas, here’s your ultimate guide to dressing for success on your next work trip.

What is Business Formal?

Think of business formal as the peak of professional attire. It’s polished, authoritative, and sets the tone for high-level interactions. While it may vary slightly by industry, the core elements remain the same:

  • Tailored pieces
  • Neutral or classic tones
  • Focus on Fit and clean, structured lines.

Industries like finance, law, and corporate leadership are often synonymous with business formal. But that doesn’t mean you have to be a Wall Street CEO to embrace this dress code. Dress for the job you want is a cliche for a reason! Dressing the part can elevate your presence, build confidence, and establish credibility before you say a word.

What To Pack for a Work Conference

Figuring out what to pack for a work conference can be simple. All you have to do is follow the Next Level Wardrobe Style System. The main principles are:

  1. Invest in high-quality staples
  2. Focus on core colors
  3. Prioritize fit

What this means in practice is this:

  • Invest in quality
    Make sure you have well-made, high-quality versions of those workhorse wardrobe pieces you need. If you need to wear a blazer to the office most days, find one you love that’ll last for years.

  • Be intentional about your color selection
    Most of your wardrobe should consist of core colors. Why? These neutral tones (black, white, navy blue, and gray) go with everything. You can always pair bold statement colors or patterns with those key basics in versatile colors.

  • Prioritize fit
    If it doesn’t fit, it’s not it. Having clothing that sits properly on your body, doesn’t bunch up, and doesn’t pull is essential. This is what makes or breaks your outfit. When pieces look tailor-made for you, you instantly look more put together and elevated.

Follow this system and packing and building an essential wardrobe should be simple. You’ll know how to mix and match pieces without stress. How do we know? Because we’ve used this system on over 300 real clients. These three steps are the key to a great off-and-on-the-clock style.

But don’t take our word for it. See the NLW Style System in action with our client, Sam.

What to Pack: Work Conference Checklist

It’s time to pack for your big conference. Here are the four pieces of business formal attire menswear you should always pack:

  1. A blazer
  2. A classic button-up
  3. Trousers
  4. Dress Shoes

Below, we’ll explain why each is a must-have and a pro styling tip.

1. Blazer

Product by Canali, shop here.

Here’s what we love about this blazer by Canali:

  • Color
    The navy blue color makes it feel more approachable and updated than a traditional black suit jacket.
  • Texture
    The texture adds visual interest and personality.
  • Fit
    The soft shoulders give off a friendly vibe, perfect for networking (and it’s also easier to pack.)

NLW Styling Tip: Heading to dinner after your day of meetings? Ditch your tie and swap your button-up for a sweater or plain gray or white tee.

 2. Classic Button-Up

Product by Reiss, shop here.

Here’s what we love about this button-up by Reiss:

  • Color
    White or light blue fits the neutral color brief while not overpowering your darker-colored blazer.
  • Fit
    The slim fit creates a more flattering look than those old baggy button-ups of the past. (You won’t look like Jim from The Office anymore.)
  • Versatile
    This button-up still works in business casual outfits for men, too. Wear it with a cropped trouser and loafers for a warm-weather look, for example. Talk about a capsule wardrobe staple!

NLW Styling Tip: Want to show off your style skills? Pair it with the blue blazer above, and you’ll achieve a monochromatic look without feeling “one-note.”

 3. Trousers

Here’s what we love about these Zegna trousers:

  • Traditional
    The crease in the front adds a dash of traditional formality.
  • Color
    You’re still working in the same dark core color palette without looking too stern. This helps your outfits feel dressed up but not stuffy.
  • Versatile
    Need to make your trousers business casual for conferences instead of formal? No worries. Partner these with a sweater instead of a button-up or a pair of white sneakers instead of dress shoes.

NLW Styling Tip: You could complete your formal or business casual conference ensemble with matching navy pants, but we prefer a mixed-separate approach. This approach offers more versatility, allowing you to wear your pants and blazer with other pieces in your suitcase. Again, it feels more contemporary and less stuffy.

4. Dress Shoes

No formal business attire (men’s edition) article would be complete without a shoe recommendation.

Here’s what we love about these derbys from Boss:

  • Classic
    The derby style is a classic. It instantly signifies a formal occasion.
  • Balanced
    The leather is the perfect in-between of glossy and unfinished. You’re not going overboard with a high-polished dress shoe. But you don’t look too casual with leather sneakers.

NLW Styling Tip: Comfy insoles are a lifesaver when you’re on your feet all day. From running around an airport to milling around conference rooms all day, insoles are non-negotiable for work trips.
