Business professional: A guide to formal business attire
‘Business professional’ refers to a more classic and strict business dress code. It is a formal, sober style that aims to convey a professional and serious image. In various work contexts, the business attire dress code is still an essential standard, whether at important meetings, presentations or in the everyday work environment of more conservative companies. In this guide, we will show you how to dress appropriately for a business professional dress code and avoid style mistakes.

In which sectors and on which occasions should you choose business professional attire?
Business professional is a formal dress code designed for conservative business environments. This style is characterised by its strictness and intention to convey an image of respectability, competence, and reliability. Wearing business professional attire indicates that the individual understands and adheres to the rules of workplace etiquette. Additionally, a sober and elegant style, which is neutral and free of excess, helps to maintain the focus on work while minimising distractions from outward appearance.

As a traditional dress code, professional business attire is particularly popular in conservative sectors such as banking, insurance, finance, law, and politics, although there can be exceptions. In these fields, especially at management levels or in roles involving frequent client interaction, adherence to this dress code is expected.
Business attire may also be required for special occasions, even if the company’s dress code is usually more casual. Important events, such as conferences, sales presentations, or meetings with significant clients, may necessitate professional business attire. Furthermore, a formal business look can be required for more celebratory occasions, such as a company anniversary.

Appropriate colours for business professional attire
To adhere to the traditional business professional attire standards, you should opt for neutral and dark shades such as black, dark blue, or grey. A subdued colour palette conveys seriousness and professionalism. Shirts and blouses can be in lighter shades like white, light blue, light grey, or pale pink, as long as they complement the colour of your dress or suit. The more formal and significant the occasion, or the higher your position within the company, the darker and more subdued the colours should be.
Tips for summer and winter business attire
If business attire is mandatory in your company, it typically applies year-round, with no exceptions for summer or winter. To avoid getting too hot or too cold, you should therefore buy suits and outfits suitable for the different seasons.
In summer, choose unlined, lightweight jackets or blazers made of breathable, cooling fabrics such as linen, cotton or seersucker. Avoid short skirts, open necklines, or open-toed shoes such as sandals, even in the warmer months.
In winter, however, you can opt for thicker, warmer materials such as virgin wool or tweed. A long, classically cut coat and accessories such as scarves, gloves and hats made of high-quality materials such as cashmere will make your business outfit suitable for even the coldest days.

Business professional outfits for men
For men, appropriate business professional attire typically consists of a formal suit and tie. You should choose a suit in darker shades, such as grey, charcoal, or navy blue, and pair it with a light-coloured shirt to create an elegant contrast. The tie should always be darker than the shirt and can include a subtle touch of colour for a refined accent. Accessories such as a waistcoat or pocket square are optional in most professional contexts. Complete the outfit with smart leather shoes, a matching belt and socks.
Here are the key items for professional business attire for men:
Formal suits in neutral and dark colours
Shirts in neutral colours
Classic black or brown leather shoes
Leather belt to match the shoes
Formal tie (without extravagant patterns)
Smart coat or trench coat depending on the season
Simple watch with leather or metal strap
Optional: pocket square, cufflinks, leather briefcase or bag
If you’re allowed to take off your jacket or blazer at work – for example outside of client meetings or on very hot days - always hang it on a hanger rather than draping it over the back of a chair.

Business professional outfits for women
Stylish clothing that fits well and is made from high-quality materials is essential for women in a business context. Unlike men, women have a wider range of options for creating a professional and understated look. A timeless classic choice is a skirt suit or trouser suit in neutral colours such as dark blue, black, or grey. Alternatively, knee-length dresses or skirts paired with a blouse or blazer make excellent options for a formal business outfit.
Here are the key items for professional business attire for women:
Trouser suits with a matching blazer
Knee-length business dresses
Blouses in light, neutral or pastel colours
Closed-toe shoes, such as pumps or loafers
A classic coat or trench coat for colder days
Optional: fine jewellery (e.g. earrings, necklaces) and a high-quality handbag or briefcase
In any case, regardless of which option you choose, keep in mind these general guidelines for women's business attire:
Skirts and dresses should reach the knee.
Pair skirts or dresses with sheer tights.
Your shoulders should be covered, even in the summer months.
Choose closed-toe shoes (with a heel of less than 7 cm).
Wear only few accessories and keep make-up simple and natural for the daytime.
Modern business professional outfits
The classic business attire can be reinterpreted in a modern way based on the industry sector. You can blend traditional silhouettes with trendy details to achieve a stylish and professional look. For men, this could mean opting for modern-cut suits, such as slim-fit options, or adding a touch of personality with subtly patterned shirts, ties, or pocket squares. Women can also choose contemporary cuts. Instead of classic pleated trousers, they might consider paperbag or wide-leg trousers, paired with an oversized blazer or delicate patterns in neutral tones, such as a chequered pattern.
Conclusion: Elegant and professional business attire
The formal ‘business attire’ dress code calls for a neat and professional appearance. The clothing choices for both men and women should ensure an impeccable fit, favour high-quality materials, and avoid overly extravagant accessories. The colour palette should remain neutral and subdued to convey competence and reliability. While this dress code may seem rigid and not very customisable, it is still possible to add a touch of personal style while adhering to the basic guidelines. Discreet accessories, small pops of colour, or simple motifs can make an outfit more unique and refined without compromising the necessary formality.
