Black tie invitations still confuse people, including plenty of men who have worn a suit to work for years. The dress code sits in an odd middle ground: stricter than a regular suit, but not quite as rigid as white tie, which leaves a lot of room for getting the details slightly wrong. Anyone helping a partner, brother, or friend get ready for a black tie event can save them a lot of last-minute panic by knowing the basics before the invitation deadline gets close.
What black tie actually means
At its core, black tie calls for a tuxedo rather than a regular suit, distinguished by satin lapels, a satin stripe down the trouser leg, and a bow tie instead of a long tie. The jacket is almost always black or midnight blue, and the shirt is typically a plain white dress shirt rather than something patterned. It is a formal but not fussy code, built around a small set of fixed choices rather than personal styling decisions.
