What to Wear to a Job Interview in the UK (By Industry)

Getting your interview outfit wrong rarely ends a candidacy on its own — but it can undermine first impressions in ways that are hard to recover from. The goal is to look appropriate for the role you are applying for, professional, and as though you have made an effort.

The General Rule

When in doubt, dress one level more formally than the company's normal dress code. If the team wears smart casual day-to-day, wear business casual to the interview. If the team is business casual, wear business formal.

You can always dress down if you are overdressed — it reads as respect for the process. Showing up underdressed is harder to recover from.

How to Research the Dress Code

LinkedIn and company social media

Photos from the office, team events, and company culture posts often show what employees actually wear. This is one of the most reliable signals.

The job description and company website

Culture sections, values pages, and "day in the life" content sometimes indicate formality.

Ask during the process

It is completely acceptable to ask the recruiter or HR contact: "Could you tell me what the dress code is for the interview?" This shows practical awareness, not insecurity.

Glassdoor reviews

Employees often describe culture and dress code in their reviews.

By Industry and Role

Law, Finance, Banking, Consulting

These sectors traditionally expect business formal: suit and tie for men, tailored suit or formal dress and blazer for women. Even where offices have adopted smarter casualness day-to-day, interview dress codes often remain more traditional.

Corporate HR, Marketing, Operations

Business formal to smart business casual depending on the company. Err towards formal for first interviews.

Tech and Startups

Smart casual is usually appropriate — clean, well-fitting clothes that look intentional. A blazer over a smart shirt or blouse works well: formal enough to show effort, relaxed enough not to look out of place in a hoodie-and-jeans culture.

Creative Industries (Advertising, Design, Media)

Smart casual with personality. Your outfit is also an expression of your aesthetic sensibility in these sectors. Quality and intentionality matter more than formality.

Healthcare, Social Care, Education

For office-based interviews in these sectors, smart casual to business casual is usually appropriate. For clinical roles where you will wear a uniform in the job, smart professional clothing works well.

Retail, Hospitality Management

Smart casual to business casual. Clean, well-presented, and practical.

Trades and Construction (office roles)

If you are interviewing for a site-based or trades role, smart casual is appropriate. A suit can feel incongruous. Clean, well-fitting clothes that look professional without being overly corporate.

Public Sector

Business casual to business formal depending on the level of the role. Senior and leadership roles typically expect formal; frontline and support roles can be smart casual.

Practical Considerations

Fit matters more than price

A well-fitting high-street suit looks more professional than a poorly fitting designer one. Whatever you wear should fit properly.

Clean and pressed

Clothes should be clean, ironed, and free from visible wear. Check for missing buttons, loose threads, and marks before the day.

Shoes

Shoes are noticed. Clean, appropriate shoes are important — particularly in more formal sectors. Trainers are acceptable in very casual environments; everywhere else, opt for something smarter.

Fragrance

Keep it light or skip it. Interviews are often in small rooms.

Accessories and grooming

Keep accessories simple. Hair, nails, and general grooming should look deliberate and clean.

Video Interviews

For video interviews, dress as you would for an in-person interview — at least from the waist up. This is practical (you may need to stand during the call) and psychological (dressing professionally affects how you feel and perform).

Avoid busy patterns on camera — they can cause visual interference on video. Plain, solid colours work better.

Use CVCircuit to build a CV that reflects the same care and professionalism as your interview presentation — because first impressions start before you walk through the door.
