How to dress for an interview? Twenty years ago, this was a simple question—pick your best suit, keep colours conservative, and avoid novelty ties. While that advice still holds value, today’s interview landscape has evolved.
Preparing for an interview goes beyond researching the company and practising answers. What you wear plays a critical role in shaping that all-important first impression. You only get one chance to make it—so it’s worth getting right.
With more relaxed workplace cultures, interview attire is no longer one-size-fits-all. Instead, your outfit should reflect the company, the industry, and the role. The good news? With a bit of preparation, it’s easy to strike the right balance.
Understanding Interview Dress Codes
There are three main types of interview attire you’ll come across: smart casual, business casual, and business formal. In addition, there’s a fourth category particularly relevant to Engineering and Manufacturing environments when on site.
Smart Casual Interview Attire
Smart casual is increasingly common, especially in modern and creative workplaces. However, never assume—it’s always worth researching the company first.
This style blends professionalism with a relaxed edge. Think polished but not overly formal.
Smart Casual for Women
Tops: Blouses, blazers, patterned tops, jumpers
Bottoms: Skirts, smart jeans, tailored trousers
Shoes: Smart flats, boots, sandals, or clean trainers
Smart Casual for Men
Tops: Oxford shirts, fitted t-shirts, blazers, button-down shirts
Bottoms: Chinos, smart jeans, trousers
Shoes: Smart trainers, brogues, casual formal shoes
Business Casual Interview Attire
Business casual is common in customer-facing roles and industries such as finance, media, and professional services. It’s more structured than smart casual but less formal than a full suit.
It’s also widely adopted across Europe and growing in popularity in the UK, often allowing for subtle personality through colour and style.
Business Casual for Women
Tops: Blouses, tucked-in shirts, blazers, cardigans
Bottoms: Tailored trousers, knee-length skirts
Shoes: Pumps, flats, heels, smart boots
Business Casual for Men
Tops: Tucked-in shirts, fine-knit jumpers, blazers
Bottoms: Chinos, smart trousers, occasional smart denim
Shoes: Loafers, Oxfords, smart boots
Business Formal Interview Attire
Business formal remains the standard for traditional sectors such as law, finance, and senior corporate roles. When in doubt for these industries, this is the safest choice.
Business Formal for Women
Tops: Blazers, suit jackets, smart blouses
Bottoms: Suit trousers, pencil skirts, dresses
Shoes: Low heels, pumps, smart flats
Business Formal for Men
Tops: Suit, dress shirt, tie
Bottoms: Suit trousers
Shoes: Polished formal shoes
On-Site Interview Clothing for Engineering and Manufacturing
In Engineering and Manufacturing, interview attire can be less straightforward due to the nature of the work environment.
What to Expect on Site
You may need protective clothing for a site tour. While most companies provide this, bringing your own safety footwear or gear can be more comfortable and practical.
Attending After Work
It’s common for candidates to attend interviews straight from work in site clothing (e.g. polo shirts and work trousers). This can be acceptable—but only if agreed in advance.
Best Approach
If unsure, bring a change of clothes. A smart casual or business casual outfit is typically the safest choice, often with slightly more durable footwear and fabrics suited to the environment.
How to Choose the Right Interview Outfit
Research the Company
Check the company’s website, social media, or employee profiles to gauge dress standards.
Ask for Guidance
If you’re unsure, ask your recruiter. Companies are often flexible—especially for graduates or early-career candidates.
Consider the Interview Format
Whether it’s in person or via Microsoft Teams, the same standards apply. Dressing well helps you feel prepared and confident.
When in Doubt, Overdress
It’s better to be slightly overdressed than underdressed. It shows effort and professionalism.
Final Tips for Interview Success
Fit Matters
Well-fitted clothing always looks more professional than items that are too tight or too loose.
Grooming Counts
Hair, nails, and overall presentation should be clean and tidy. Attention to detail makes a difference.
Choose Fragrance Carefully
Avoid overpowering scents. Subtle, office-appropriate fragrances are best.
Prepare the Night Before
Lay out your outfit in advance to avoid last-minute stress.
Make the Right First Impression
Dressing appropriately shows that you understand the company culture and take the opportunity seriously. It also helps you feel confident and prepared—an often overlooked advantage.
Combine the right outfit with strong interview preparation, and you’ll put yourself in the best position to succeed.
