Black tie

You are most likely to see this one on an invitation. “Black tie” indicates that the guests are expected to wear evening attire, which for men specifically means a black tuxedo. Apart from the tuxedo, evening attire consists of a dress shirt, bow tie, plain black socks (no pattern), and black shoes, for example patent leather shoes. Cummerbund and waistcoat are optional.

Business Formal

One of a variety of business styles. Although it is less restrictive now than it used to be, it still specifically defines what is appropriate to wear for work. It is a formal style, observed by legal, consulting, and financial corporation employees, politicians, diplomats, and guests at formal receptions . “Business formal” implies a dark suit (navy blue or dark grey), an elegant plain white or light blue shirt with a stiff collar (any model apart from button-down), dark tie, leather shoes and a matching belt.

Business Smart

The most common, everyday business dress code seen in corporations and public offices, less formal than the restrictive “business formal”. It gives you more freedom and allows you to add a touch of individual style while maintaining a professional and elegant look. “Business smart” consists of a suit in a sombre colour (trousers and jacket made of the same fabric), a light-coloured shirt — either plain or with a delicate pattern (striped or pin-striped). Button-down collars and patterned ties, as well as brown shoes are also permitted.

Smart Casual

In other word: sporty chic — this style is a combination of elegance and comfort. Instead of a suit, a silk tie and grey or navy blue socks, think sports jacket, chino trousers, a knitted tie, and bolder socks that may even feature bright colours or patterns. You may also wear a shorter jacket made of wool, or a different heavy fabric, and in the summer — a lighter version made from airy linen. A jacket with a houndstooth, check or other small pattern will add a touch of refinement.

Casual

This dress code is just what the name promises — effortless, informal, and laid-back. It is rarely seen in a professional environment, although it is perfectly appropriate for informal meetings with colleagues outside of work. It comprises casual elements, which nonetheless create a consistent look. Men can take off their jackets and relax in casual trousers.
