What Should I Wear to a Job Interview in London?

London interviews come with a particular anxiety: the city’s industries have wildly different dress codes, and getting it wrong feels like failing before you’ve spoken. Turn up in a full suit to a Shoreditch startup and you look like you don’t understand the culture; turn up in jeans to a City law firm and you look like you don’t want the job. I once overdressed so badly for a media interview that the hiring manager laughed — kindly — and told me to lose the tie. “what should I wear to a job interview in london” — let’s get into it properly, with the detail and straight talking the question deserves.

This guide breaks down what to wear by industry, the universal rules, budget-friendly formulas, and the details that actually register with interviewers. Because what you wear won’t get you the job — but it can stop you losing it in the first thirty seconds.

The universal rules (every industry, every role)

Fit beats price, always. A £60 suit that fits looks better than a £300 suit that doesn’t — budget for alterations (£15–£30 for trouser hemming and waist suppression) if needed. Everything clean, pressed, and lint-free: check under good light before leaving, not in the hallway mirror. Shoes polished or clean; scuffed shoes are one of the first things interviewers notice, fairly or not.

Grooming matters more than fashion: neat hair, trimmed nails, minimal fragrance (one spray or none — interview rooms are small), and no chewing gum, ever. Keep jewellery and accessories minimal and quiet — one statement piece maximum. Your outfit should be forgettable in the best way: the interviewer should remember what you said, not what you wore.

Practical London considerations: check the weather and plan for the commute — arrive early enough to cool down, de-rain, and compose yourself. Bring a bag that fits your documents neatly; a bulging carrier bag undermines the whole effect. And silence your phone completely, not just vibrate.

What to wear by industry

Corporate (law, finance, consulting, insurance): full suit still rules. Men: navy or charcoal suit, white or light blue shirt, conservative tie, Oxford shoes. Women: suit (trouser or skirt), blouse, closed-toe heels or smart flats. This is the one context where traditional is safest — the City hasn’t casualised as much as people claim. Budget option: M&S or Next suit (£80–£150) plus alterations.

Creative/media/tech: smart casual with intention. Dark jeans or chinos, a blazer or smart jacket, clean minimal trainers or boots are fine in most startups — but elevate one level above the company’s daily dress. If their Instagram shows hoodies, wear a blazer; if it shows blazers, wear a suit. Women: midi dress with blazer, or tailored separates. The goal is “I respect this opportunity” without “I don’t understand your culture.”

Public sector/charities/education: smart but not corporate — the full City suit can look out of place. Tailored separates, a dress with a blazer, or a suit without a tie reads right. Healthcare: smart casual; you’ll often be told scrubs or uniform expectations after hiring. Hospitality/retail: neat, brand-appropriate, practical shoes. When in doubt, email HR or the recruiter — “What’s the dress code for the interview?” is a perfectly professional question.

Corporate: full suit, conservative, traditional
Creative/tech: elevated smart casual, one level above company norm
Public sector: smart separates, not full corporate
Always: ask the recruiter if unsure — it’s expected

Budget-friendly interview outfits

You don’t need a new wardrobe. Men: navy blazer (£50–£80, Uniqlo/M&S) + grey trousers + white shirt + tie = interview-ready for under £150, and every piece works separately afterwards. Women: black midi dress (£30–£50) + blazer + simple flats = under £120 and endlessly reusable. Charity shops in good areas often have barely-worn suits for £15–£30 — worth checking before buying new.

Borrowing is underrated: a friend’s blazer for the day is free and often better quality than what you’d buy. Just ensure fit is reasonable and return it cleaned. And remember that men can buy good suits under £200 — there’s no need to spend more for interview purposes.

The night-before checklist: try on the full outfit (including shoes and bag), check for stains, missing buttons, and loose threads under bright light, iron or steam everything, lay it out ready, and check the weather forecast for outerwear planning. Morning-of panic is how details get missed.

Details that actually matter (and mistakes to avoid)

Interviewers form impressions fast, and small signals register: a well-fitting outfit signals attention to detail; appropriate dress signals cultural awareness; neat grooming signals professionalism. None of this is about beauty or expense — it’s about showing you take the opportunity seriously.

Common mistakes: too much fragrance (the top complaint), wrinkled clothes, novelty ties or loud patterns (save personality for your answers), visible underwear lines or straps, overdone makeup or very long nails in conservative industries, and — the classic — new shoes that hurt, making you walk strangely and fidget. Break shoes in beforehand (see breaking in heels).

For virtual interviews: dress fully, not just the top half — you’ll feel more professional and there’s always a chance you’ll need to stand. Check your background, lighting (face the window), and camera angle. And the same rules apply: the interviewer can see wrinkles and stains on camera just fine.

The interview hall of shame: what not to wear

Learn from others’ mistakes. Too much fragrance is the number one interview complaint — interview rooms are small and scent is inescapable; one spray maximum, or none. Wrinkled clothes signal carelessness louder than any answer signals competence; steam or iron the night before, no exceptions. Novelty ties, loud patterns, and statement fashion risk making you memorable for the wrong reasons — save personality for your answers.

Shoes deserve special attention: scuffed, dirty, or overly casual shoes (trainers at a corporate interview, unless it’s that kind of company) undermine everything above them. New shoes that haven’t been broken in cause visible discomfort — fidgeting, strange walking, wincing — which reads as nervousness. Break them in for a week first.

Other classics: visible underwear lines, chewing gum (never, ever), sunglasses on the head, overdone makeup or very long nails in conservative industries, and the full-length puffer worn indoors through the interview (take it off — it photographs in memory as sloppy). None of these reflect your ability; all of them affect snap judgments. The goal is invisibility: clothes so appropriate they’re unremarkable.
