How to Dress for a Job Interview

Your interview outfit has one job: to let the interviewer focus on what you say, not on what you are wearing. It does not need to be expensive, fashionable, or memorable. It needs to look right for the workplace you are walking into, fit you properly, and feel comfortable enough that you forget about it once the conversation starts.

This guide is about outfits only. What to say in the interview, and how to prepare your answers, is covered in our companion guide on how to prepare for a job interview.

The one rule that governs everything

Dress one level more formally than the people who work there wear on an ordinary day. If the team wears suits every day, you wear your best suit. If the team wears chinos and shirts, you add a blazer. If the team wears jeans and trainers, you wear dark, tidy trousers and a collared shirt. You are not copying the office dress code exactly. You are showing that you understand it and have made an effort for the occasion.

If you cannot find out what the team wears, there is a safe default. A navy or charcoal suit with a white or light-blue shirt and dark leather shoes works for most interviews, with a tie for formal sectors such as finance, law, consulting, and government, and an open collar where the setting is clearly less formal.

How to find out what the team wears

Check the employer’s website and social media pages first. Team photos, “about us” pages, and pictures from office events usually show what people actually wear at work. The job description sometimes helps too — words such as “business dress” or “smart casual” are clues — although employers use these labels differently, so what people actually wear is the more reliable guide. If a recruiter is arranging the interview, ask them directly: “What do people usually wear in the office?” Recruiters expect the question.

What to wear at each level

Workplaces fall roughly into four levels. Use the description of what people wear day to day, rather than the label, to work out which one applies.

Business formal. Suits and ties every day, often in law, finance, consulting, government, and senior corporate roles. For men: a tailored suit in navy, black, or dark grey, a white or light-blue shirt, a silk tie, and polished leather shoes. For women: a trouser suit, skirt suit, or a structured dress with a blazer. This is the top step, so you match it rather than going above it.

Business professional. One step below formal, common in many corporate offices, professional services, and sales. A suit is still the safest choice, with a tie optional, or a navy blazer with grey trousers and a collared shirt. For women: a tailored suit, a blouse with tailored trousers, or a modest knee-length skirt with a blazer.

Business casual. Blazers, dress trousers, collared shirts, and no tie — the everyday dress of many offices, and one of the most common interview dress codes. For men: tailored dress trousers with a collared button-down shirt, tucked in, plus a smart blazer. For women: a crisp blouse with tailored trousers or a modest knee-length skirt, with a structured cardigan or blazer. Shoes are dress shoes or loafers for men, and refined flats, loafers, or low heels for women, all in good condition and neutral tones.

Casual. Jeans, T-shirts, and trainers are everyday wear in many tech firms, start-ups, and creative agencies. Even here, an interview calls for a step up: dark chinos or dark, non-ripped jeans, a collared shirt or a fine knit, an unstructured jacket if you own one, and clean, plain shoes. For women: dark denim or tailored trousers paired with a blouse. If the culture is genuinely unclear, business casual is the safest middle ground for many roles.

Colours, fit, and fabric

Neutral colours are the safest choice: navy, black, charcoal, and grey, with a white or light-blue shirt or blouse. They look professional, photograph well on a video call, and do not distract. A coloured shirt, a subtle pattern, or a restrained accessory can add personality, but the base of the outfit should stay quiet. Loud colours, large logos, and busy patterns pull attention away from your face, which is where you want the interviewer looking.

Fit matters more than the label on the garment. A well-fitting suit from an ordinary shop looks better than an expensive one that is too big or too tight. The jacket should sit cleanly on your shoulders, the sleeves should show a small amount of shirt cuff, and the trousers should break gently at the shoe rather than pooling around it. A skirt should sit at knee level or below, a guideline recommended by university careers advisers. Try a new outfit on while sitting down as well as standing up, because you will spend much of the interview seated.

Choose fabric for comfort, especially if the interview is long or the weather is warm. Natural fibres such as wool and cotton breathe better than many synthetics, and a wool-blend suit usually holds its shape through a day better than a pure synthetic one. Whatever you choose, make sure it is clean, pressed, and free of creases, stains, and pet hair. Iron your shirt, polish your shoes, and check the outfit in daylight before the day arrives.

What to avoid

Some things are almost always wrong for an interview, whatever the workplace: graphic T-shirts, hoodies, athleisure, ripped jeans, shorts, sandals, and trainers. So are clothes that are too revealing, too tight, or too short, and anything with a slogan, a large logo, or a strong scent. Keep fragrance light or skip it altogether, because a strong perfume or aftershave can be distracting in a small meeting room.

Keep accessories subtle: one or two pieces of simple jewellery, a classic watch, a plain belt, and a tidy bag or portfolio. Avoid anything that jingles, flashes, or needs to be fiddled with. Your phone should be silent, out of sight, and out of mind.

Do not wear anything brand new for the first time on the day itself. New shoes can pinch, a new shirt can itch, and a new jacket can pull in places you did not notice in the shop. Wear anything new at home first — sitting and standing — so you know it is comfortable before it matters. Comfort equals confidence, and an outfit you keep adjusting is working against you.

Dressing for a video interview

Video interviews follow the same rule as in-person ones: dress as though you were going into the office, one level above the everyday norm. Dress fully, including trousers, because you may need to stand up or adjust the camera. Solid, muted colours work best on camera; fine stripes, small checks, and bright white can shimmer or glare. Navy blue, dark grey, and black are the safest colours on a video call. Before the call, sit where you will sit, turn on the camera, and check the framing, your collar, and the background behind you. Sit facing a window or a lamp, not with a bright window behind you.

The night before and the morning of

Lay out the whole outfit the night before — including shoes, belt, bag, and accessories — and check each piece for stains, creases, loose buttons, and scuffed shoes. Try it on once, sitting and standing, and walk around in it for a few minutes. Put your documents and identification in your bag the night before, so you are not searching for them in the morning. On the day, give yourself more time than you think you need, arrive early enough to check your appearance, and take a breath before you walk in.

Common questions

Should I wear a suit if the office is casual? A full suit can look overdressed in a very casual workplace, but a blazer with dark trousers and a collared shirt usually hits the right note. Dress one level above the everyday norm, not three levels above it.

Is it all right to wear black to an interview? Yes. Black, navy, and charcoal are all safe, professional choices. Black works well with a white or light-coloured shirt or blouse to avoid looking too severe.

What shoes should I wear? Polished, closed-toe shoes in a neutral colour: leather Oxfords, Derbies, or loafers for men, and refined flats, loafers, or low, comfortable heels for women. Make sure you have worn them before.

Can I wear jeans to an interview? Only if the workplace is genuinely casual, and then only dark, clean, non-ripped jeans with a collared shirt or a smart top and clean shoes. In a formal or business-casual workplace, tailored trousers are the safer choice.

What if I cannot afford a new outfit? You do not need one. A clean, well-fitting outfit you already own, pressed and polished, will serve you better than a new one that does not fit. Spend your effort on fit and grooming rather than on shopping.

Should I dress differently for a second interview? Wear something similar in formality, but not necessarily the same outfit. If the second interview is with senior staff or a client-facing team, leaning slightly more formal is sensible.

The bottom line

Dress one level more formally than the team wears on an ordinary day, choose neutral colours and a proper fit, and wear something comfortable enough to forget about. Research the workplace first, lay the outfit out the night before, and try it on sitting down as well as standing up. Avoid anything loud, casual, or brand new on the day, and dress fully for a video call just as you would in person. Your clothes will not get you the job on their own — but the right outfit makes sure nothing about how you look gets in the way of what you have to say.
