Black tie
The most formal dress code at most weddings and galas. Wear a black or midnight-navy tuxedo with satin lapels, a white formal shirt, a black bow tie and polished black shoes. See tuxedo vs suit for the details.
Formal
A step below black tie. Wear a dark suit — black, navy or charcoal — with a white shirt, a classic tie and black shoes. A tuxedo is also acceptable for evening formal events.
Cocktail
Popular for engagement parties and evening celebrations. Wear a well-fitted suit in any classic or rich colour. A tie is optional; a pocket square adds polish.
Business (business formal)
For offices, meetings and interviews: a navy, charcoal or grey suit, a white or light-blue shirt, a conservative tie and leather shoes.
Smart casual
A blazer with tailored trousers, or a relaxed suit without a tie. A knit polo or open-collar shirt works well.
