Guys' Office Style for Every Dress Code

Take the guesswork out of getting dressed

By Style Girlfriend | Last Updated: Jul 25 2019

Building a capsule wardrobe for your off-duty style is a great way to feel like a million bucks every time you get dressed. But what about at work? Too often, guys see office style – and their office dress code – as an excuse to dress, well…lazy and boring, if we’re being honest.

Which is a bummer! Because you can look as cool and stylish at work as you do on the weekends with just a little bit of effort.

How to understand office dress codes for men

You may not get much guidance on office style when you start at a new job. HR might reference the dress code in your interview, but you’re really best off scoping the style of your potential new co-workers as you walk through the office. Maybe it’s a casual, start-up work environment, with everyone in jeans and sneakers. Or maybe it’s investment banking and everyone shows up in a suit minus the jacket but plus a company fleece.

Having these kind of unofficial dress code guardrails can be helpful when building a work wardrobe. Hey, you’ve got to start somewhere!

Why dressing well at work matters

But you shouldn’t stop at “Well I’ll just wear what everyone else is wearing.”

First, because that’s boring.

And second, because there’s a good chance you’ll perform with more confidence in your professional duties if you’re dressed in a way that makes you feel amazing.

You can shine in day-to-day office style, no matter the office dress code.

Below, the guy’s guide to office style for every dress code:

Of course, there’s plenty of variation in degrees when it comes to office dress codes. Especially for workplaces where there’s technically no dress code, which we’d argue is even more confusing.

If you ascribe to the idea of dressing for the job you want, it’s worthwhile to stock your closet with clothes that will leave you at the upper end of any office’s baseline style.

First up? The casual—or non-existent!—office dress code…

1) Casual Office Dress Code

Office style for guys in a casual workplace

SG Says: The casual dress code is the least dress code-y of any workplace. It basically means, “Don’t show up in cutoff jean shorts, but honestly we don’t care.” This kind of non-dress code is prevalent in tech and start up culture.

Which is great for your wallet, since you won’t have to invest in both a work and weekend wardrobe. However, don’t use a casual office dress code as an excuse to show up to the office looking sloppy.

Pro tip: Well-fitting items like slim- or straight-fit dark jeans, un-rumpled sport shirts, and leather sneakers are all good casual dress code staples. Even a t-shirt in a heavier fabric (and that’s free of stains, obviously) can work in a casual office.

2) Business Casual Dress code

SG Says: A business casual dress code is a step up in terms of formality from casual office style. You can (probably) still wear your jeans, but instead of a t-shirt, you’ll be wearing a sport coat and oxford shirt.

Pro tip: When it gets chilly, layer with a light sweater and not a company-branded fleece. Please.

3) Business Professional Dress code

SG says: A “business professional” dress code is just a few style zhushes away from the most formal dress code, which is (you guessed it) “business formal.” You’re wearing a suit…but maybe without a tie. Or you’re wearing a sport coat with dress pants, instead of jeans.

Pro tip: When you have a big client meeting, or are speaking in front of a large group, dress one level above your usual dress code. So, if you’re in a casual office, dress in a “business casual” outfit on the big day. If you work in a business casual-dress code office, dress in “business professional” for that do-or-die client meeting.

4) Business Formal Dress Code

SG Says: The most formal of dress codes, you definitely will know if you’re getting yourself into a “business formal” environment before your first day. This dress code is mostly reserved for more traditional professions like banking.

Pro tip: Don’t let the need to wear a suit every day turn you lazy with your clothes! You can show your personal style with touches like interesting shirt and tie combinations, snazzy socks, and unexpected accessories.
