What’s This About:
A common rule for a job interview is to dress one level more formally than the team wears on an ordinary day, and when you cannot find out, a navy or charcoal suit is the usual safe choice.
This guide answers the questions men ask before an interview, such as:
– suit or no suit, and how to find out before you walk in
– what to wear for a formal, business-casual, casual or practical workplace
– which colours, fabrics and shoes work best
– what changes in summer, in winter and on a video call
– which mistakes recruiters mention
and many more!
Each workplace level has its own outfit, and the checklist at the end is the one to run the night before.
Key Points:
01One level up: find out what the team wears on a normal day, from the careers page, social media or the recruiter, and dress one step more formally than that.
02If you cannot find out, a navy or charcoal suit with a white or light-blue shirt and dark leather shoes is a safe default; wear a tie for formal sectors and judge the rest.
03Fit matters more than price: well-hemmed trousers and the right sleeve length do more than an expensive label.
04Clean, pressed and quiet: no creases, stains or pet hair, light or no fragrance, and nothing you will need to adjust while you talk.
The Short Answer
Dress one level more formally than the people who will interview you wear on an ordinary day.
Careers advisers recommend this approach because it ties the outfit to the workplace rather than to a fixed idea of “interview clothes”, from a law firm to a warehouse.
Robert Half’s guide advises aiming one level above the company’s everyday dress code, and TailorCV’s 2026 guide gives its governing rule as “dress one level more formal than the team’s daily norm”.
When you cannot find out what the team wears, the default is a navy or charcoal suit with a white or light-blue shirt and dark leather shoes, with a tie for finance, law, consulting and government and an open collar where the setting is clearly less formal.
The sections below give the outfit for each level, the way to find out which level applies and what changes for summer, winter and a video call.
How to Find Out What the Team Wears
A few minutes of research replaces most guesswork.
Start with the company’s careers page and social media; The Muse suggests looking for photos of the team at work on a normal day and then stepping the formality up a level unless the team already wears suits.
Robert Half gives the same advice and adds the direct route of asking.
Asking is not a weakness: “what do people usually wear in the office?” is a question recruiters and interview coordinators answer regularly, and the answer tells you the level.
If the interview is for a client-facing role, consider dressing for the clients as well as the office, and ask if you are unsure.
Then place the answer on the ladder below and go one step up.

| What the team wears daily | Level | What you wear to the interview |
|---|---|---|
| Suits and ties every day (often law, finance, consulting, government, senior corporate) | Business formal | A dark suit, white shirt, tie and leather Oxfords; this is the top step, so match it |
| Blazers, dress trousers, collared shirts, no tie (many corporate offices, professional services, sales) | Business professional | A suit, tie optional; or a navy blazer with grey trousers, tie optional |
| Chinos, button-downs, knits, clean denim (many offices) | Business casual | A blazer or sports coat, wool trousers or chinos, a collared shirt, leather loafers or Derbies |
| Jeans, T-shirts, trainers (many tech firms, start-ups, creative agencies, some charities) | Casual | Dark chinos or dark jeans, a collared shirt or fine knit, an unstructured jacket if you own one, clean plain shoes |
| Uniforms, work boots, aprons (trades, retail, hospitality, warehouse, food service) | Practical | Clean chinos or dark jeans, a plain collared shirt or polo, clean closed shoes; neat and practical |
Employers and careers sites use these labels differently, especially “business formal” and “business professional”, so use the description of what people actually wear rather than the label alone.
What to Wear, Level by Level
Business Formal: Law, Finance, Consulting, Government
A navy or charcoal suit, single-breasted with two buttons, in a plain cloth or subtle pattern; a white or light-blue shirt with a spread or point collar; a plain or small-pattern tie in navy, burgundy or dark green; black or dark-brown leather Oxfords or Derbies; a belt that suits the shoes; and dark socks that cover the calf.
Robert Half describes this level as fully coordinated suits, dress shirts and polished shoes, typical of law firms and senior finance roles, and TailorCV recommends a “well-fitting suit in a dark neutral” for these sectors.
In settings like these a suit is the norm rather than overdressing, and the interviewer will probably be wearing one.
Wear the jacket into the room and keep it on unless you are invited to take it off.
Business Professional: Corporate Offices, Professional Services, Sales
The same suit with the tie optional, or a navy blazer with mid-grey wool trousers, a light-blue shirt and brown leather shoes.
Robert Half lists tailored blazers and dress trousers for this level, and Indeed’s interview guide recommends “a dark-colored suit” for a formal workplace.
The tie is the easiest adjustment: wear one if the team photos show ties, leave it off if none do, and carry one folded in your bag if you are unsure.
Our business formal and business professional guides cover the wardrobes behind these two levels.
Business Casual: Many Offices
A navy, grey or brown blazer or sports coat; wool trousers or chinos in grey, navy, tan or olive; a collared shirt, button-down or plain, in white, light blue or a small check; leather loafers, Derbies or clean leather boots; and a belt that suits the shoes.
Indeed suggests a button-down shirt for business-casual settings, and Robert Half’s description of the everyday level includes chinos, knitwear, button-downs and clean denim.
The blazer is the step up: the team wears the trousers and shirt every day, and the jacket shows you prepared for the interview.
In cooler months a fine-gauge knit under the blazer can replace the shirt.
Our business casual guide and business casual shoes guide cover the wardrobe in detail.
Casual: Tech, Start-ups, Creative Agencies, Some Charities
Dark chinos or dark straight-leg jeans with no distressing; a collared shirt, such as a plain or small-pattern Oxford, or a plain fine-gauge knit; an unstructured blazer or smart overshirt if you own one; and clean leather trainers, loafers or desert boots.
TailorCV warns that a suit can look like a misreading of a casual culture, with the example of “a three-piece suit at a ten-person startup”, and Robert Half describes the casual everyday level as well-kept jeans, plain T-shirts, jumpers and clean trainers, so the interview step up is the collar and, if you have one, the jacket.
Creative roles allow personality in colour or pattern, while your portfolio still does most of the talking.
Our smart casual guide is a useful reference for this level.
Practical: Trades, Retail, Hospitality, Warehouse, Food Service
Clean chinos or dark jeans without rips; a plain collared shirt or polo, tucked in; clean closed-toe shoes, or clean work boots if the interview includes a walk around the floor; and no hat, hoodie or large logos.
TailorCV’s advice for trades, retail and operations is “neat and practical”, and Indeed suggests dark jeans or trousers with a button-down shirt or polo for a casual workplace.
A suit is rarely needed at this level, and clean, pressed, practical clothes show you are ready to start work; if the job advert or the invitation says otherwise, follow it.
If the interview includes a site tour, ask whether you need safety footwear or other protective equipment.
For a first retail or restaurant job, the details matter more than the garments: clean shoes, a shirt that fits, and tidy hair and hands.
Colours, Fabrics and Shoes
Navy and charcoal are the usual interview colours for suits and jackets because they look serious without the evening associations of black or the summer feel of light grey and tan.
White and light-blue shirts sit well under every jacket colour and with most ties.
If you wear a tie, choose a plain weave or a small repeating pattern in navy, burgundy or dark green, tied in a four-in-hand or half Windsor; our guide to tying a tie covers both knots.
Wear black or dark-brown leather shoes, polished the night before, with a belt in a colour that suits them; loafers suit business casual and below, and trainers suit only the casual level, clean and plain.
Choose fabrics that hold a crease and resist creasing on the journey, such as wool or wool blends for suits and trousers and cotton poplin or Oxford cloth for shirts.
Fit matters more than any of this: TailorCV’s summary is “fit beats price”, and the recruiter comments collected by Washington State University’s apparel department include the advice “Hem those pants!”
A tailor’s adjustment to trouser hems and jacket sleeves is one of the cheapest improvements available, whether the suit is new or old.
Summer, Winter and Video Interviews
Summer: keep the jacket for formal and business-professional interviews, in a lighter cloth such as tropical wool, cotton or a linen blend at the more casual levels, and wear it into the building; a short-sleeved shirt under a jacket is the summer shortcut to avoid.
Winter: wear an overcoat over a suit or blazer for formal interviews, and if the weather calls for boots, carry your shoes and change in the lobby; take the coat off before the interview room.
Video interviews: dress in the whole outfit, not just the top half, because you may need to stand up; the University of Bath careers service also advises dressing smartly including your bottom half.
Robert Half notes that clean lines and solid colours look better on camera than busy patterns, and TailorCV advises that mid-tones read best, along with contrast against your background, minimal jewellery and a test on camera in the same light before the call.
What Not to Wear: Mistakes Recruiters Mention
Trousers that pool on the shoes and sleeves that cover the knuckles; the recruiter comments collected by Washington State University include more than one comment about unhemmed trousers.
Overdressing for a casual culture or underdressing for a formal one, which TailorCV describes as misreading the culture.
Brand-new shoes you have not walked in, and any garment that needs adjusting while you talk.
Creases, stains and pet hair; Indeed’s checklist is to “ensure clothing is pressed and wrinkle-free” and to “check for pet hair, holes or stains”.
Strong fragrance; Indeed advises keeping any scent light so it is not overpowering.
Untidy facial hair; the Washington State University recruiters commented on facial hair as bluntly as on any garment, so trim or shave the day before rather than the morning of, to avoid razor marks.
A sloppy knit in place of a jacket: the same panel called a sweatshirt-style jumper “too sloppy” for an interview.
Loud accessories, novelty ties, a bag that does not close and a phone that is not silenced.
The Night-Before Checklist
Lay out the whole outfit, including socks, belt and the bag or folder, and put it on once to check that it fits and stays put when you sit down.
Press the shirt and trousers, polish the shoes, and check every surface for lint, hair and stains in good light.
Check the weather and decide on the coat, the shoes for the journey and where you will change if needed.
Trim your beard or shave, cut your nails, and book any haircut for earlier in the week rather than the day before.
Put a folded tie, a lint roller and a spare pair of socks in your bag.
Silence your phone before you enter the building.
If religious dress, a disability or a health condition affects what you can wear, you do not need to change it to fit a convention; you can mention any practical needs to the recruiter if you wish.
Common Questions
Q. How should men dress for a job interview?
One level more formally than the team wears every day: a suit for formal sectors, a blazer with trousers for business-casual offices, a collared shirt with chinos or dark jeans for casual workplaces, and clean practical clothes for trades and retail.
When you cannot find out, wear a navy or charcoal suit with a white or light-blue shirt.
Q. Is it overkill to wear a suit to an interview?
In finance, law, consulting and government, usually not, because suits are common there.
In a tech start-up, a creative agency or a trade, a suit can look out of step, and a blazer with chinos or a clean collared shirt is often the better level; if you are unsure, ask.
Q. What should a man wear to a casual job interview?
Dark chinos or dark jeans without rips, a collared shirt or a plain fine knit, an unstructured jacket if you own one and clean, plain shoes; casual means one step up from the team’s T-shirts.
Q. What should a young person wear to a first job interview?
The practical level: clean chinos or dark jeans, a plain collared shirt or polo tucked in, clean closed shoes and no hat or hoodie; a suit is rarely expected for a first retail or restaurant job, and clean and pressed is what the manager looks for.
Q. What colour suit is best for an interview?
Navy first, charcoal second: both work with a white or light-blue shirt, brown or black shoes and most tie colours.
Q. What should I wear to a video interview?
The full outfit for the level, in solid mid-tone colours that contrast with your background, with no fine patterns, tested on camera in the same light before the call.

Mandy Meyer’s focus at The VOU is men’s body-shape styling, garment fit and outfit proportions. Her coverage addresses the practical questions behind a wardrobe choice: how a jacket sits across the shoulders, how trousers fall and how different cuts change the silhouette a wearer wants to create.
Her subject areas include the triangle, inverted triangle, rectangle, oval, trapezoid, hourglass and diamond labels used in body-shape styling. These provide starting references for comparing visible proportions; they do not capture every body or prescribe one correct way to dress. The focus connects those observations with garment shape, construction, length and the relationship between the upper and lower parts of an outfit.
Mandy’s editorial coverage combines visual comparisons with fit checks for comfort and movement. Readers can consider whether a cut gives them the room they need, where clothing pulls or gathers and which changes might support their preferred look. The aim is to make menswear choices more understandable while keeping personal preferences and the wearer’s own styling goals central.
