Short answer: dress one step more formal than the role's daily dress code. For most corporate and client-facing interviews that means a navy or charcoal suit with a white or light blue shirt and a conservative tie. For tech, startups and creative roles, a collared shirt with chinos and a blazer. For trades and field roles, clean work-appropriate clothing with a collared shirt. When you genuinely can't tell, ask the recruiter — it's a normal question.

The one rule that decides everything

Find out how people dress in the role, then go one step up the ladder. Not two. Showing up in a full suit to a startup interview where everyone wears hoodies signals that you haven't looked into the company; showing up in a polo to a law firm signals the same thing in the other direction.

Ways to find out, in order of reliability: ask the recruiter directly, look at the company's team page or LinkedIn photos, or look at how they dress in any recent video content.

By industry

Corporate: law, finance, consulting, insurance, real estate

Wear: a navy or charcoal suit, white or light blue dress shirt, conservative tie, black or dark brown leather dress shoes, matching belt.

This is the one context where a full suit remains the expectation rather than a choice. Navy is the strongest default — charcoal is equally correct, black reads formal or funereal in daytime business settings.

Avoid: a loud tie, a patterned shirt that competes with the tie, and a jacket and trousers that don't quite match.

Tech, startups, product and engineering

Wear: a collared shirt — solid or subtly patterned — with chinos or dress pants and leather shoes. A blazer is optional and rarely wrong; you can carry it and decide at the door.

Most tech offices run casual, so a suit overshoots. Business casual with one deliberate upgrade is the target.

Avoid: a tie without a jacket (it reads unfinished in this context), and a graphic tee under a blazer.

Teaching and education

Wear: a collared shirt with dress pants or chinos, leather shoes. Tie and blazer for administration and secondary; optional for elementary.

Schools are usually business casual day to day, so an interview sits at smart casual. Comfort matters more than in most interviews — you may be walking a campus or teaching a sample lesson.

Healthcare

Wear: business professional or a step below — dress shirt, dress pants, tie for most clinical and administrative roles. Suit for leadership positions.

Even where the daily uniform is scrubs, interviews are dressed.

Trades, construction, logistics and field roles

Wear: clean, undamaged work-appropriate clothing with a collared shirt. A button-down or polo with sturdy trousers and clean boots.

A suit is the wrong signal here — it suggests you don't understand the job. A pressed collared shirt shows you take the interview seriously without pretending the work is something it isn't.

Retail, hospitality and customer-facing

Wear: one step above the store or venue's uniform. For most, a collared shirt and chinos; for upscale venues, add a blazer or a tie.

Video interviews

The dress code doesn't change, but three things do:

• Dress the bottom half too. You will stand up at some point.
• Avoid tight patterns. Narrow stripes and small checks can shimmer on camera. Solids and larger patterns are safer.
• Mind the contrast. A white shirt against a white wall washes out. Light blue is the most reliable on-camera dress shirt color.

The details that get noticed

• Wrinkles. The most common failure and the most avoidable. If you're traveling to the interview, the shirt needs to survive the journey.
• Collar structure. A collapsed collar makes an otherwise good outfit look tired, and it's the first thing to go on a shirt that's been washed a lot.
• Fit at the shoulders. The one thing a tailor can't easily fix on a jacket, and the one that decides whether a suit looks bought or borrowed.
• Matching leathers. Belt to shoes. More here.
• Sweat. Interviews are warm. A shirt fabric that shows perspiration works against you for an hour you can't get back.

Common questions

Should I wear a suit to a job interview?

For corporate, legal, financial and client-facing roles, yes. For tech, startups, trades and most casual workplaces, a collared shirt with chinos and an optional blazer is a better read of the room.

What color suit is best for an interview?

Navy first, charcoal second. Both read as professional without drawing attention. Black is best saved for evening and formal events rather than daytime interviews.

Do I need a tie for an interview?

For corporate and client-facing roles, yes. For tech and casual workplaces, a tie without a jacket often reads as unfinished — a collared shirt alone is the stronger choice.

What should I wear to a video interview?

The same as an in-person interview for that industry. Favor solid colors over tight patterns, avoid white against a white wall, and dress the bottom half as well.

Is it bad to be overdressed for an interview?

Slightly overdressed reads as respectful. Significantly overdressed — a full suit at a company where nobody owns one — suggests you didn't research the company. One step up is the target.

Can I ask what to wear to an interview?

Yes, and you should if you're unsure. Asking the recruiter is normal, low-risk and gets you a better answer than guessing.
