Business casual is one of those dress codes that causes more confusion than any other. Too formal and you risk looking overdressed for the office. Too casual and you may look like you didn’t try at all. The sweet spot sits somewhere in the middle, and shirts are at the centre of getting it right.
At Tapered, we know that fit matters just as much as fabric or colour. Our office shirts are engineered with a unique tapered cut for men with broad shoulders and a narrow waist, so you always look sharp without excess fabric.
But before we get into why fit is everything, let’s first break down what business casual actually means.
What is Considered a Business Casual Shirt?
A business casual shirt bridges the gap between a formal dress shirt and an everyday casual top. It should look polished enough for the office while being comfortable enough for daily wear.
Oxford shirts, button downs in plain or subtle patterns, and even polos in the right context all qualify. The goal is balance: smart enough to convey professionalism, relaxed enough that you don’t look like you’re on your way to a board meeting.
What is Business Casual Dress Code UK?
In the UK, business casual is often more conservative than in the US. Men are expected to avoid extremes — no ripped denim, trainers, or flashy prints. The most reliable formula is a collared shirt paired with chinos.
Oxfords, linen shirts in warmer months, and polos in creative or tech-driven offices all fall comfortably within the UK definition, provided the rest of your outfit is pulled together with smart footwear and a clean silhouette.
What Shirts are Business Casual?
Business casual encompasses collared shirts that avoid extremes. Oxford shirts, button-downs, tailored linen shirts, and polos in plain, neutral colours are all safe choices. Subtle patterns like stripes or small checks can also work, as long as they don’t overpower the outfit.
In summer, breathable fabrics like cotton and linen help keep you comfortable while maintaining structure. In cooler months, twill or poplin shirts add a touch of refinement. Pairing these shirts with chinos or tailored trousers ensures the overall look stays sharp.
Ultimately, business casual shirts should bridge the gap between smart and relaxed, making you look polished without appearing overdressed.
What is Not Considered Business Casual?
Not everything with a collar qualifies as business casual. T-shirts, graphic designs, oversized cuts, flannel, and jersey fabrics are too casual. Similarly, sleeveless styles or anything excessively short-sleeved fail to project professionalism.
Do and Don'ts of Dressing Business casual
The best way to approach business casual is to think of it as “professional, but approachable.” The foundation of a strong look starts with fitted collared shirts in neutral tones — crisp whites, soft blues, light greys, and subtle patterns like pinstripes or micro-checks. These shades pair easily with chinos or tailored trousers and give you endless versatility.
Fabrics matter too. Lightweight, breathable cotton or linen keeps you comfortable all day, while ensuring your shirt holds its shape through meetings and commutes. Always finish the look with smart shoes such as loafers, brogues, or clean leather trainers if your workplace allows.
Where many men go wrong is mistaking business casual for simply “casual.” Avoid anything baggy or poorly structured, as it makes even expensive pieces look sloppy. Shiny fabrics like polyester blends or satin often appear cheap under office lighting and should be kept for nights out.
Weekend wear — graphic T-shirts, hoodies, oversized flannels, or heavily distressed denim — undermines professionalism instantly. Even subtle missteps, like wearing sandals or sports trainers, can pull your outfit out of the business casual zone.
Another key mistake is going too loud with colours and prints. A bright floral or neon shirt might be fun socially, but in a business context it can be distracting and give the impression that you’re not taking the environment seriously.
If you want to introduce personality, do it subtly — for example, through a muted check pattern, a textured Oxford shirt, or adding depth with a navy or olive polo.
Ultimately, business casual works best when you strike a balance: clean, tailored clothing that feels comfortable, but always looks intentional.
Think of a navy Oxford shirt paired with beige chinos and brown loafers, or a pale blue linen shirt worn with grey trousers and leather Chelsea boots. These kinds of outfits project confidence and style without going over the top, making them timeless business casual choices.
Are Short Sleeves Business Casual?
Short sleeve shirts can absolutely fall into the business casual category, but context is everything. In warmer months or more relaxed office environments, a well-fitted short sleeve Oxford or button-down shirt in a neutral colour can look sharp when paired with chinos or tailored trousers.
The key is fit — short sleeves that are too loose or too long risk looking sloppy, while those cut too tight may come off as casual weekend wear.
Polos also work well as short sleeve business casual options, particularly in offices with a more modern dress code. To keep the look professional, avoid bold logos or overly bright colours and stick with clean, minimal designs.
In more traditional workplaces, long sleeves may still be the safer choice, but short sleeves can provide a smart, comfortable alternative when styled correctly.
What Colour Shirt is Business Casual?
When it comes to business casual, colour plays a bigger role than most men realise. The safest and most versatile options are neutrals — crisp white, light blue, pale grey, or soft pastels. These shades instantly project professionalism and pair effortlessly with trousers, chinos, or even dark denim in workplaces that lean more relaxed.
A white Oxford shirt with navy chinos is a timeless combination, while a pale blue shirt with grey trousers offers a subtle, refined contrast that works in any office.
That doesn’t mean your palette has to stay boring. Earthy tones such as olive, camel, or muted burgundy can also look sharp, particularly in autumn and winter, while soft pinks or lilacs can work well in spring and summer.
The key is subtlety: stick to shades that don’t overpower the rest of your outfit. Think of them as accents to freshen up your rotation without breaking the business casual mould.
What you’ll want to avoid are overly bright colours, flashy patterns, or novelty prints. A bold floral or neon green shirt may feel confident for a weekend out, but in a professional setting it can come across as distracting or unpolished.
Similarly, very dark colours like all-black can feel too formal or even a little harsh for day-to-day wear, unless they’re balanced with lighter trousers or layers.
A good rule of thumb is to consider the setting. Creative agencies may embrace more colour and pattern, while corporate offices tend to prefer conservative, understated shades.
Are Oxford Shirts business casual?
Yes. The Oxford shirt is a staple of business casual dress. Its thicker weave gives it structure, while the button-down style makes it versatile. Worn with chinos, it looks effortlessly polished; paired with smart trousers and loafers, it leans closer to formal.
Can You Wear a Denim Shirt to the Office?
Denim shirts sit on the casual edge of business casual. A dark-wash denim shirt, cut slim and paired with chinos, can work in a relaxed office environment. Lighter washes or distressed denim, however, lean too far into weekend wear and don’t suit the workplace.
Can You Wear Linen Shirts to the Office?
Linen shirts are an excellent option for summer, especially in offices without strict formal codes. They’re breathable and lightweight, keeping you cool while still looking smart. Stick to light colours such as white, pale blue, or stone, and make sure the cut is tailored — an oversized linen shirt will appear sloppy rather than stylish.
Can You Wear a Polo Shirt to the Office?
Polos often sit right on the edge of business casual. In more relaxed offices, especially in tech or creative sectors, a well-fitted polo in a neutral colour works perfectly. It should always be paired with smart trousers rather than jeans to maintain the right balance.
At Tapered, our polos are engineered with the same tapered fit as our shirts, so you get a flattering, sculpted look without the bagginess you often find elsewhere.
