Workplace culture has shifted significantly, moving away from the rigid 9-to-5 routine—and with it, the classic suit-and-tie dress code is fading. As a result, expectations around professional attire have evolved too. One of the most notable shifts is the rise of business casual, a concept that blends professionalism with comfort. While it might baffle those from previous generations, even many modern men still find the term unclear and open to interpretation.
What Does Business Casual Mean for Men?
Business casual for men is a contemporary dress code that strikes a balance between professional polish and relaxed comfort. It moves beyond the traditional suit-and-tie, offering a neat, intentional look without feeling overly formal.
Admittedly, the definition can feel a bit ambiguous—and that’s because it is. Business casual can vary greatly depending on personal style, industry standards, and company culture. The goal is to look respectful while still expressing individuality. To help make sense of it all, we’re breaking down the key elements that will help you confidently craft a business casual outfit that’s both appropriate and authentic to you.
The Evolution of Business Casual
While “business casual” might sound like a modern concept, its origins go back several decades—shaped by cultural shifts and changing workplace norms.
The concept of business casual emerged in the 1960s, when U.S. companies began introducing “Casual Fridays”—a move designed to boost employee morale by relaxing the dress code at the end of the week. Fast forward to the 1990s, and the tech boom in Silicon Valley brought a major shift. A new wave of CEOs and developers abandoned corporate formalities, favoring comfort and self-expression. Ties gave way to T-shirts, and dress shoes were swapped for sneakers—eventually influencing the broader corporate landscape.
Today, business casual attire for men is widely accepted. However, what qualifies as business casual can still vary significantly depending on the region, industry, and specific company culture.
TOPS
Traditionally, a business top consisted of a dark, solid-colored suit jacket worn over a white long-sleeved dress shirt, paired with a matching black or dark-colored tie.
To ease into a more relaxed business casual style, start by removing the tie. Leave the top button of your dress shirt undone and wear your suit jacket open for a more effortless look. If you still want to incorporate a blazer, pay attention to its color. Dark hues like black, navy, and charcoal maintain a more formal, classic business appearance. For a true business casual feel, opt for lighter shades such as beige, light blue, or grey—or experiment with non-traditional tones and patterns like coral, olive, or even subtle checks to inject personality while staying polished.
BOTTOMS
Equally important is the fit and style of your bottoms. Loose-fitting trousers project a laid-back feel, while very slim or tight-fitting styles can also come across as more casual, especially when paired with softer tops. Cropped pants or full-length trousers with a turned-up cuff add an extra relaxed element, helping to round out your business casual look with an effortless touch.
Naturally, denim jeans are among the most casual options for business casual attire. While they’re widely accepted in many modern workplaces, not all styles are suitable for every office setting. The best choice for a polished yet relaxed look is slim-fit or straight-leg jeans in a dark wash, with a clean, non-distressed finish and a hem that rests neatly at the shoe.
On the more casual end of the spectrum are baggy jeans, skinny fits, and bootcuts. Cropped or cuffed jeans also lean toward a more laid-back appearance. When it comes to color, the rule is simple: the lighter the wash, the more casual the vibe. Think stone-washed, medium blue, white, or even khaki jeans—all of which can work well for a softer take on business casual.
Accessories
Shoes speak volumes about your overall look. Classic leather Oxfords, Derbies, and Monk Strap shoes remain timeless choices—even in modern office settings—and pair well with most business outfits.
For a more relaxed business casual vibe, consider loafers. Horsebit, penny, and tassel loafers are excellent options, especially when matched with chinos or dark jeans. They strike the right balance between sophistication and ease.
