Whitetie
White tie is the most formal evening dress code. Men wear a black tailcoat, formal trousers, a white waistcoat and a white bow tie with an evening shirt. Women wear a full-length formal gown. Read the host’s instructions closely and arrange any hire early, because a dinner suit does not meet the traditional code.

Confirm the details
A ceremonial invitation can specify decorations, national dress or other details. Ask the organiser about those requirements. General fashion advice cannot replace instructions for that event.
Allow time to fit it
If hiring, try the full outfit together before collection. Check the shirt, waistcoat and coat as a set, and practise walking and sitting in the shoes and clothing.
Good to know
Is white tie the most formal dress?
White tie sits at the most formal end of traditional evening dress. It is a precise code, so follow the invitation and any additional instructions from the organiser.
How to wear a white tie?
Wear a white bow tie with the correct evening shirt, white waistcoat and black tailcoat. A white necktie with a regular suit does not create a white-tie outfit.
What do ladies wear to a white tie event?
The traditional choice is a full-length formal evening gown. Check the host’s instructions about gloves or ceremonial details. Short dresses and trousers fall outside the traditional code.
What is a dress code for a black tie event?
Black tie uses a dinner jacket and black bow tie. White tie requires a tailcoat and white bow tie. Confirm which wording appears on your invitation before arranging hire.
