Black tie’s numerous variations reflect its origin as informal dining attire and its later role as semi-formal cocktail attire.  White tie, on the other hand, originated as the most formal type of civilian apparel and has retained that exclusivity for over two centuries.  When it transitioned from formal evening dress to special evening dress after the Second World War its definition became fixed.  Fashion designers may attempt to alter the tailcoat’s features from time to time but style and etiquette experts recognise that the fundamentals of full dress (as white tie is also known) are not open to interpretation.

The following definition is drawn from fifty authoritative British & American resources published over the past seventy years.

Gentlemen who receive an invitation to a white-tie affair should use this definition only as a starting point.  Considering that full dress is required solely for the most illustrious of social events and that its garments are not nearly as forgiving a dinner suit, it is important to familiarise yourself with the components of white tie before visiting your tailor, buying or renting the required attire.
