Business Casual for Men: Dress Code Guide

As the workplace norms of previous generations continue to adapt to modern times, so too do the dress codes. For proof, consider the men’s business casual dress code, a broader and thereby more liberating take on the kind of formal attire once worn by Don Draper and his ilk. Picture a cotton blazer with a dress shirt and no tie and you’re heading in the right direction.

That said, the business casual dress code remains a somewhat elusive concept lacking in clearly defined rules and principles. For example, it’s hard to know what’s acceptable when it comes to business casual pants, jackets, slacks, and corporate office wear. Give such loose parameters, it’s no wonder that so many professional men out there are still wondering what exactly constitutes the men’s business casual dress code. For the answer, look no further than our Business Casual Guide for Men below. We’ll get you up to speed in no time.

What is Business Casual Attire for Men?

By definition, business casual attire is a style that’s not quite as formal as traditional office wear, but nevertheless still designed to render a professional or business-like impression. Naturally, that leaves plenty of room for interpretation. Not helping is the inclusion of the word “casual”, which historically imparts visions of men in Hawaiian t-shirts, shorts and sandals. To that we would say: just go ahead and try wearing truly casual wardrobe to the office on a regular workday and see how far it gets you. In other words, business casual is still far more “business” than it is “casual”, and that’s definitely a good thing.

Hence, when wearing business casual attire, you’re still expected to abide by the customary principles of style and sophistication. However, where business professional dress once constituted oxford shirts and stuffy suit jackets, it’s now morphed into a slightly more nuanced office styling. A (preferably tailored) blazer is always a safe bet, as is a dress shirt. Ties are optional, but what you lack in neckwear you should make up for in fashion sense. And while some business casual-friendly offices permit a nice pair of jeans, make sure it’s a really nice pair of jeans. Otherwise, stick with quality trousers like cotton chinos to have an ensemble that’s safe for the ol’ work environment. In the shoe department, comfortable dress shoes like loafers, Oxfords, monk straps and derbies are an easy way to abide. And don’t forget to make sure everything matches, also known as “duh”.

History of the Business Casual Dress Code

It wasn’t too long ago that most professionals would have considered the term “business casual” to be an outright oxymoron. Casual slacks? What are those? Nevertheless, times change and so do dress codes. As for the history of business casual attire, it can, in fact, be linked to the concept of “casual Fridays”, which reportedly has origins in Hawaii during the 1960s. That was when the Hawaiian garment industry helped push for the idea of “Aloha Fridays”, where men were encouraged to wear Hawaiian shirts to work at the end of the week. Jump ahead to the early 90s, and the concept had finally reached mainland USA in the form “casual Fridays”. Since then, men’s casual office wear has continued to explode.

However, what some men considered to be casual Friday work clothes was a little too casual in the eyes of their bosses. To fill the void, Dockers–which specialised in weekend wear and had been recently acquired by Levi’s–made a crucial pivot into the business casual sphere. To boost awareness during the transition, the Dockers marketing team sent an eight-page brochure entitled “A Guide to Casual Businesswear” to over 25,000 human resource departments across the United States. Naturally, Dockers khakis were absolutely central to the new business casual dress code.

Like something out of Dockers’ wildest dreams, more and more offices began to embrace khaki pants as being allowable workplace attire, five days a week. As such, a new precedent spread like wildfire throughout the late 90s and early 2000s. However, along the way, the Dockers style get-up became synonymous with cubicle workers and low-level employees, prompting a revision of sorts. The new business casual dress code–which presented a somewhat looser approach to formal attire–was thus born. The way men dress in their office environment would never be the same.

Men’s Business Casual Examples

Hopefully, you’re getting a solid feel for what the business casual dress code is all about. To help move you further along, here are some tips and suggestions from neck to toe. Your standard work wardrobe is going to be forever transformed.

Business Casual Blazers

Your business casual outfit starts with a nice blazer, and by “nice” we mean tight and tailored. To that end, the blazer should tout a slim cut, a square fit on the shoulders, a lapel that stops right above your rear end and sleeves that stop just before the shirt cuff. Naturally, you have a range of styles and materials to choose from. Your safest bet is to get a classic single-breast blazer of light wool with peak or notch lapels, which will keep you comfortable no matter what the season. Opt for a dark, neutral colour like navy–it will do wonders for your figure. This business casual style will help you rock the office while giving you something to wear out after work at happy hour.

If you’re the type who likes to dress according to the season, a tweed blazer is the way to go during those cold winter months. Again, aim for neutral colours like navy or grey, expanding your palette as you get more confident with your business casual wardrobe. And for the warmer seasons, a quality cotton or linen blazer can do you know wrong.

Underneath that stylish blazer, you’ll want to rock a tasteful button-down shirt like a trusty Oxford. The business casual shirt should have two straight seems in the back and cling tightly to the shoulders and frame. When first starting out, stick to monochromatic colours light white, light blue or light pink. As you gain more confidence, you can explore different patterns and brighter colours, being sure to keep your sense of fashion within reason.

Also worth noting is that more and more men are pulling off the no-blazer look, going instead with a tight-fitting sweater or button-down cardigan in colours like navy or gray. Underneath that should be a collared shirt, and if you’re wearing a cardigan, a tie. One last pointer: keep those armholes high to further retain a tight, professional vibe. This code guide is designed to show you the possibilities for your office wear while keeping you well within the confines of what’s considered business “professional.”

Business Casual Pants

Now that straight up suit pants are no longer mandatory, you have options. However, it’s important to stress that your business casual trousers should emanate with as much sharpness, intent and sophistication as the rest of your outfit. Thats means wearing clean, tight-fitting trousers, though they shouldn’t be so tight that you’re suffocating the boys–slim is the operative word here. Along similar lines, a pair of crisp, mid-weight cotton chinos with flat fronts and a neutral aesthetic will never steer you wrong. And if you’re going with denim, that’s okay, but it should be denim that’s as high in quality as a pair of premium dress slacks. It’s pretty easy to differentiate high-quality denim from casual denim, and everyone at your next business meeting will be able to tell.

Business Casual Shoes

Given the broad parameters of the men’s business casual dress code, there are a range of acceptable shoes, all of which have two things in common: quality and style. To play it safe, we recommend sticking with modern dress shoes such as polished loafers, Oxfords or monk straps, in materials like leather and colours like chocolate, dark red or tan. When you’re ready to experiment (in an office that allows for it), slip on a nice pair of suede ankle boots or chukkas. And if your boss is cool with it, you can rock some leather sneakers, but those sneakers better be immaculate and expensive when it comes to work wear. Even a more casual workplace will expect this standard.

Perhaps the most beautiful thing about the men’s business casual dress code? That the tie is optional. Of course, that doesn’t automatically mean you shouldn’t wear one. If and when you do, keep it classic in colour, and consider materials like silk. However, if you ask us, we say ditch the tie and make your accessory of choice a distinguished wristwatch with a leather strap. Also, don’t forget to grab yourself a professional leather bag that makes space for your gadgets and paperwork alike. Now you’re hustling like a 21st-century businessman.
