The moment you receive an interview invitation, a mix of excitement and anxiety sets in. While you’re busy preparing for the tough questions, there’s one crucial detail that can make or break a first impression: your attire. In the United Kingdom, where professional etiquette and unspoken rules are deeply ingrained, knowing what to wear isn't just about looking good—it’s about showing respect for the company and the role.
The days of a one-size-fits-all approach to interview outfits are long gone. What’s appropriate for a job in a London banking firm would be completely out of place at a tech startup in Manchester. Dressing correctly shows that you understand the company’s culture and are already a good fit. This comprehensive guide will walk you through the golden rules of UK interview attire and provide specific advice for a range of key industries.
Before we dive into the specifics, these fundamental principles apply to virtually every interview, regardless of the industry.
This is the single most important rule. Before you even think about your wardrobe, investigate the company’s culture. Look at their website, especially the "About Us" or team pages, to see how current employees dress. Check their social media for recent event photos. Is everyone in suits, or are they wearing smart-casual attire? This is your biggest clue. When in doubt, a quick search on LinkedIn for employees in similar roles at the company can also give you insight.
No matter the dress code, a clean and professional appearance is non-negotiable.
Clothes: Ensure your clothes are clean, ironed, and free of stains or wrinkles.
Shoes: Your shoes should be clean and polished. Avoid scuffed or worn-out footwear.
Grooming: Hair should be tidy and neatly styled. Nails should be clean. Be mindful of perfume or aftershave—a subtle scent is fine, but anything overpowering can be a distraction.
If you're unsure about the dress code, it's always safer to be slightly overdressed than underdressed. It's easier to remove a jacket or tie to adjust to a more casual setting than it is to appear more professional on the spot. Dressing up signals that you take the opportunity seriously.
Wear clothes that make you feel confident and comfortable. If you’re constantly fidgeting with an ill-fitting blazer or struggling to walk in uncomfortable shoes, it will show. The goal is for your outfit to be an afterthought, allowing you to focus entirely on your interview performance.
The UK's diverse job market means that "interview attire" can mean many different things. Here’s a breakdown by industry.
This is the most traditional and formal sector. The dress code is strictly professional and conservative.
For Men: A well-fitting two-piece or three-piece suit is a must. Stick to classic, conservative colours like navy blue, charcoal grey, or black. Pair it with a long-sleeved, collared shirt in a solid colour (white or light blue are classic choices). A silk tie with a subtle pattern is appropriate, but avoid anything loud or novelty. Polished leather shoes (oxfords or brogues) are essential.
For Women: A tailored business suit (a skirt suit or trouser suit) is the standard. Opt for a skirt of a professional length (just at or below the knee). A classic blouse or a smart shirt, in a solid colour or with a subtle pattern, works perfectly. Closed-toe, modest heels or smart flats are suitable footwear. Keep accessories minimal and professional.
This sector is known for its relaxed culture, but don't be fooled—professionalism still matters. The key here is smart-casual or business-casual.
For Men: Leave the suit at home. Smart chinos or well-fitting dark jeans paired with a clean, collared shirt (button-down or polo) is a safe bet. A smart knitted jumper or a blazer can be added for a polished look. Smart trainers (the clean, minimalist kind) or leather loafers are appropriate footwear.
For Women: Smart, well-fitting trousers or a stylish skirt with a blouse or high-quality t-shirt. A blazer or smart cardigan can elevate the look. Heels are usually not expected; stylish flats or smart trainers are perfectly acceptable. The goal is to look put-together, creative, and comfortable.
This is where you can show a bit of personality and style, but it's important to remember that it's still a professional setting. The dress code is a blend of smart and creative.
For Men: This is a good opportunity to experiment with textures and layers. A blazer over a smart t-shirt or a unique shirt can work well. Smart trousers or stylish dark jeans are acceptable. Think about a nice pair of smart shoes or fashionable boots.
For Women: A smart dress with a unique cut, a stylish skirt-and-blouse combination, or smart trousers with a fashionable top are all great choices. You can incorporate more colour or interesting accessories than you would in a corporate setting, but avoid anything that could be distracting. The key is to look fashionable, but not overly trendy or unprofessional.
For these sectors, the focus is on a clean, practical, and approachable appearance that projects a sense of trustworthiness and competence.
For Men: A full suit might be too formal. Smart trousers and a collared shirt are a good choice. You can add a tie and blazer if you want to elevate the look, but it’s not always necessary. The priority is to look tidy and professional.
For Women: Smart trousers or a professional skirt paired with a simple blouse or smart top is ideal. A smart cardigan or a blazer can be worn over the top. Flat, comfortable, and clean shoes are a must, as these roles often involve being on your feet.
The dress code here is about looking clean, presentable, and friendly. The level of formality depends on the brand.
For Men: Smart-casual is the general rule. Smart trousers or dark jeans with a collared shirt or a smart polo shirt. If it's a high-end brand, a blazer might be appropriate.
For Women: Smart trousers or a skirt with a blouse or smart top. Flats or low heels are a good choice. For high-end retail or fine dining, the expectations will be much higher, potentially requiring a smart dress or a full business-casual look. Always check the brand's style beforehand.
While knowing what to wear is important, knowing what not to wear is just as crucial.
Anything Wrinkled or Dirty: A wrinkled shirt or stained trousers immediately signals a lack of care and attention to detail.
Overly Casual Items: Unless you're specifically told to, avoid t-shirts, ripped jeans, sneakers, and sandals.
Distracting Accessories: Keep jewelry, patterns, and loud colours to a minimum. You want the interviewer to focus on your words, not your attire.
Strong Scents: Avoid heavy perfume, cologne, or aftershave. A subtle scent is fine, but a strong one can be off-putting in an enclosed space.
Your outfit is only part of the equation. Your overall presentation is what ties everything together.
Hair and Makeup: Hair should be neat and styled. For makeup, a natural and professional look is best.
Nails: Ensure your nails are clean and well-kept.
Bag: A professional bag or briefcase is a good choice to carry your CV, notepad, and pen. Avoid carrying a rucksack or a casual bag.
Ultimately, your interview attire is your first opportunity to show respect for the role and the company. By doing your research and choosing an outfit that aligns with the industry and your own personal confidence, you’re already one step closer to making a lasting positive impression.
Good luck!
