Here's what the 6 major men's dress codes really mean
Black-tie, informal, business casual - what does it all actually mean?
In order to demystify invitation dress codes, we consulted "The Pocket Butler," an etiquette guide written by longtime butler Charles MacPherson. In his book, MacPherson breaks down the dos and don'ts of those seemingly simple invitation dress requirements.
A perfect business casual outfit includes pants that aren't jeans, a sports coat, and a dressier shirt. A tie is not required. The idea is to appear relaxed but put-together.
Business dress is what those who work in finance and law wear on a daily basis. It's code for a suit and tie, but with a little more freedom to get creative.
Semi-formal or informal
You might be relieved to know that semi-formal is not a synonym for black-tie; the two dress codes are completely separate.For semi-formal, all you need is a dark colored suit with a dress shirt and tie. Nothing too fancy is required, but the rules are a little more restrictive than business dress.
If you see "black-tie optional," know that a tuxedo is not required, but whoever sent the invitation will most likely be wearing one.
An appropriate black-tie optional outfit could include a navy or black suit with a formal dress shirt and a dark-colored tie. And yes, you can wear a tuxedo if you like.
Black-tie is often considered the pinnacle of modern formality.
It usually includes a completely black tuxedo with a white formal shirt, finished with a black satin bow tie. Sometimes a black satin cummerbund is added, but that is becoming less and less common. Black socks and black patent leather shoes are non-negotiable for black-tie.
This style of dress differs from black-tie in that the tie is white (surprise), a white vest is required (and quite starchy), and the coat has tails. White gloves are optional.
