What to Wear to an Interview
One rule covers almost every case: dress one level above the everyday standard of the team you are joining. A well-judged outfit gets no comment at all — which is exactly the point.
One Level Above the Team
Not one level above the industry, and not the most formal thing you own. One level above the people you would sit next to.
It signals that you took the occasion seriously without suggesting you have misread the culture. It is the narrow band where clothing stops being a topic.
A formal suit in a room where nobody owns one reads as a poor culture read — and culture read is something interviewers actively assess.
Matching the everyday standard exactly can read as casual about the process. The small lift is what marks it as a deliberate choice.
How to Find Out the Dress Code
You almost never have to guess. Six ways to find out, starting with simply asking.
"Is there a dress code I should know about, or is the team fairly casual?" It is a normal question, it takes one line in an email, and the answer is usually specific enough to end the guesswork.
Team photos and office videos are staged, but they still tell you what the company considers presentable. If everyone in the photos is in a t-shirt, a three-piece suit will feel like a costume.
Recent LinkedIn or Instagram posts from people who actually work there — conference photos, team days, office moves — show the real everyday standard rather than the brand version.
'Casual, come as you are' and 'please dress smartly' both appear in real invitations. If the email tells you, believe it rather than overriding it.
For a factory, hospital, kitchen, or site-based role, ask whether you will be walking the floor. Safety footwear and practical clothing may matter more than a jacket.
If every source is silent, dress one level above what you believe the team wears. It is the reliably safe direction to be wrong in.
Four Levels, With Actual Outfits
Pick the level, then pick whichever build suits how you dress. None of these depend on who is wearing them.
Law, investment banking, senior finance, some government and executive roles
A matched dark suit — navy, charcoal, or black — with a pressed white or pale blue shirt.
A tailored dark skirt suit or trouser suit with a plain blouse or fine knit.
Polished leather closed-toe shoes; a dark leather belt matching the shoes.
Minimal jewellery, a plain watch, a structured bag or slim portfolio.
Fit is the whole game at this level. A well-tailored inexpensive suit reads better than an expensive one with the shoulders in the wrong place.
Corporate roles, consulting, accountancy, insurance, larger established companies
A blazer with contrasting trousers or a skirt — the jacket is what does the work.
A shirt, blouse, or plain fine-gauge knit in a solid colour.
Leather shoes, loafers, or low block heels — clean and unscuffed.
A dark, structured bag; a single piece of jewellery rather than several.
The safest default for any interview where you genuinely cannot find out the code. Almost no corporate environment reacts badly to this.
Mid-size tech, marketing, education, healthcare administration, most modern offices
Chinos or tailored trousers with a shirt, blouse, or knit — no tie needed.
A casual blazer or an unstructured jacket, which you can remove if the room is more relaxed than expected.
Clean leather shoes, smart loafers, ankle boots, or plain minimal trainers.
One considered detail — a good watch, a decent bag — rather than several.
Bringing a jacket you can take off is the single most useful hedge in interview dressing. You can dress down in ten seconds; you cannot dress up.
Early-stage startups, creative studios, agencies, trades and hospitality front-of-house
Dark, clean jeans or chinos with a well-fitting plain top or shirt.
A knit, overshirt, or casual jacket as the layer that lifts it above everyday wear.
Clean, plain trainers or casual boots — condition matters more than formality here.
In creative fields, one deliberate personal element is an asset rather than a risk.
Casual is not the same as unconsidered. Everything should be clean, fitted, and obviously chosen for the occasion.
Ten Industries, Ten Defaults
Use these when you have no company-specific information at all.
Suit, every round, including video. This is one of the few sectors where under-dressing is genuinely counted against you.
Client-facing standard applies from the first interview. Blazer minimum; suit for final rounds.
Chinos and a shirt or knit is the standard read. Suits are unusual and can feel out of step.
Dark jeans and a good top is normal. Bring a layer in case the founder turns out to be more formal than the office.
Taste is part of the assessment. Considered and individual beats safe and corporate here.
Conservative and practical. Closed shoes, minimal jewellery, nothing that would be impossible on a ward.
Slightly more formal for school and university panels than for edtech companies.
Ask whether you will be on site. Sturdy footwear and workwear in good condition often reads better than a jacket.
Look at what the floor staff wear and go one level above it. Brand fit is genuinely part of the assessment.
Conservative and unremarkable. Panel interviews here reward looking like you already work there.
Dressing for a Video Interview
Same level of formality, different technical constraints. A webcam is not a mirror.
Pure white blows out under most webcam exposure and black loses all detail. Mid-blue, grey, olive, and burgundy all hold up.
Narrow stripes and small checks create moiré patterns that shimmer on compressed video and pull the eye away from your face.
A mirror tells you nothing about how a fabric reads through a webcam. Join a test call and look at yourself in the actual lighting.
You may need to stand for a delivery, a document, or a whiteboard. This is a well-worn cautionary tale for a reason.
A dark top against a dark wall makes you a floating head. Choose a colour that separates you from whatever is behind you.
Bracelets and long earrings that knock against a desk or a headset are surprisingly loud on a microphone.

The Details That Actually Get Noticed
Fit and condition, in that order. Both matter far more than what anything cost.
The single highest-return adjustment is a tailor taking in a jacket or shortening a hem. It costs little and changes how everything reads.
Creased, bobbled, or visibly worn clothing undoes an otherwise correct outfit. Steam or press the night before, not the morning of.
Clean and unscuffed matters more than expensive. It is the detail people report noticing most often after the interview.
Some offices are formally fragrance-free and some interviewers are sensitive. Clean and neutral is the safer choice.
If you are adjusting a waistband or standing in painful shoes, that attention is coming out of your answers. Wear it for an hour at home first.
Any adaptation you need — seated-friendly cuts, easy fastenings, supportive footwear — takes priority over convention. Nobody is assessing your buttons.
Plan for arriving damp or overheated. A coat you can remove and a bag that protects your documents solve most of it.
Including shoes, bag, and documents. Deciding what to wear an hour before an interview costs attention you need for the interview.
And six things to leave at home
A first outing reveals every problem at the worst moment — a collar that will not sit, a hem that rides, a shoe that pinches.
They invite a reaction you cannot predict and add nothing. Plain is not boring in this context, it is neutral.
Both read as someone in transit rather than someone present. Put them in your bag before you enter the building.
Not clothing, but the same category of avoidable distraction. Silent, not vibrate, and in a bag rather than on the table.
Flip-flops, beach sandals, and worn-through trainers undercut everything above them, including in casual industries.
Anything you have to hold, tug, or rearrange to sit down will occupy you for the whole conversation.
