The idea of “office attire” in the UK has changed a lot in recent years. Ties and suits are now rare sights in many workplaces, replaced by smart jumpers, crisp polos, and comfy shoes. A blend of “smart casual” and the so-called “corp-core” aesthetic is driving this change. Businesses up and down the country are having to rethink their dress codes. Here’s what’s happened, why it matters, and what your business should think about next.
The Decline of Strict Dress Codes
Strict dress codes are fast becoming a thing of the past. Not long ago, you wouldn’t step into a meeting without your jacket and tie. But, according to recent data, only 4.3% of UK employers still enforce a formal dress code—a huge 80% drop in the last few years.
What’s sparked this change? Remote work played a huge role. During the pandemic, people swapped office-wear for home comforts, often working in trackies, jumpers, or even pyjamas. For many companies, it quickly became clear that productivity isn’t linked to whether someone’s wearing a tie or not. If anything, people worked better when they felt comfortable. Even senior leaders were seen on conference calls in hoodies rather than blazers. The culture changed and, frankly, most workers don’t want to go back.
What Does “Smart Casual” Actually Mean?
“Smart casual” is a phrase that pops up a lot, but it can mean different things in different offices. At its core, it’s about blending elements of formal and informal wear—enough polish to look professional, but relaxed enough to be practical and comfortable.
Typical smart casual staples:
- Smart trousers, chinos, or dark jeans
- Polo shirts, plain jumpers, or blouses
- Clean trainers, loafers, or boots
- No ties required, but a jacket or blazer is still welcome
Smart casual gives your staff freedom to adapt their outfit according to the day ahead—maybe a crisper look for client meetings, jeans and a jumper for a regular day at the desk.
This isn’t just about comfort. It’s about staff being able to show a bit more personality at work. A wider range of styles, a better fit for different ages and body types, and less pressure to ‘fit in’ with an old-fashioned corporate look.
Enter “Corp-Core”: Mixing Function with Fashion
If smart casual is about relaxing the rules, “corp-core” is about embracing the best of classic corporate styles in a modern way. Think of comfortable fabrics, easy-to-care-for materials, and designs that look sharp in the office but don’t feel stuffy.
Corp-core is showing up everywhere—from high-street shops (lots of smart basics) to employee uniforms. Look for things like:
- High-quality basics (oxford shirts, structured cardigans)
- Versatile outerwear (trench coats, fitted blazers)
- Workwear-inspired touches (utility trousers, practical pockets, easy layering)
The goal is to make office style both practical and relevant. If you run a business, embracing elements of corp-core lets you offer a simple, unified look for staff without being rigid or old-fashioned.
Why Office Dress Codes Matter for UK Businesses
Changing your dress code isn’t just about looking trendy. It affects how your staff feel, how your business is seen, and even how you attract new talent.
Key benefits of flexible dress codes:
- Staff morale and comfort: People perform better when they’re comfortable and allowed to express themselves within reason.
- Diversity and inclusion: Dress codes that are too strict can be especially challenging for those with specific cultural, health, or personal needs. A flexible approach takes everyone into account.
- Attracting younger talent: Younger workers often expect more relaxed rules. A rigid dress code can put off strong candidates.
- Reflecting your brand: The way your team dresses speaks volumes about your business culture and the values you stand for.
That said, not every role or industry can go full “anything goes.” Customer-facing teams, those in manufacturing, or staff needing PPE still have practical requirements. That’s why a tailored, common-sense approach matters: set out what’s expected in your business, but keep it practical and realistic.
Industry Differences: One Size Doesn’t Fit All
Smart casual means different things in different sectors. In creative or tech industries, jeans and trainers often pass the test. In finance or law, it still means smart trousers and shirts—even if ties rarely appear.
When staff move between industries, they might get caught out. One company’s idea of smart could be another’s version of “too casual.” That’s why it pays for businesses to spell out what’s acceptable and offer clear guidelines.
Common approaches:
- Tech/startups: Chinos, t-shirts, smart trainers, and jumpers get the green light.
- Professional/finance: Blazers, button-downs, smart dresses, no denim.
- Creative/media: Relaxed fits, patterns, statement trainers, but tidy.
If you’re setting your own policy, think about your client base, the work you do, and the trends you see in your sector.
The New Face of Uniforms
For businesses with uniforms—think retail, hospitality, or even trades—the corp-core trend is shifting what uniforms look like. You’ll see more:
- Breathable, stretchy fabrics
- Mix-and-match pieces
- Subtle branding (embroidered logos, discreet colour accents)
- Options that suit different body types and weather
Uniforms can now look smart without being restrictive. Good design means happier staff, and your business still looks sharp to clients and customers.
Sustainability and Adapting to the Future
Workwear for 2025 is all about adaptable clothing made from sustainable materials. With eco-friendly fabrics becoming the norm, uniforms and standard office wear are both getting greener. This appeals not just to staff, but to clients and new recruits keen to work for businesses that care about the future.
Hybrid and remote working are here to stay. Office dress codes will keep evolving—but the focus will stay on practicality, comfort, and purpose. As the workplace changes, so should the way we dress for it.
Tips for Updating Your Dress Code Policy
If you’re considering a shift—or a total rewrite—of your office dress policy, here are some tips to keep things straightforward:
- Consult your team: Ask for opinions across departments and job roles. Comfort, practicality, and representation matter.
- Start with “smart casual” as a base: Offer clear examples and a few do’s and don’ts.
- Accommodate different needs: Consider adjustments for those with cultural, religious, health, or practical requirements.
- Share real-life examples: Use photos of acceptable looks (your own staff, where possible) instead of just a list of rules.
- Review regularly: Fashion and expectations change—revisit your policy at least annually.
