Verdict: black tie is full evening wear, cocktail is smart but shorter and simpler. If you are unsure which applies, check the invitation or ask the host.

Dress code meanings vary by region and event. These are general guides.

Pick black tie if

  • The invitation says black tie
  • The event is a gala, a formal wedding or an awards night

Pick cocktail if

  • The invitation says cocktail, semi-formal or dressy casual
  • The event is an evening party or relaxed formal wedding

Rule: when in doubt, go one step more formal and remove an accessory.

Common mistakes

  • Treating "black tie optional" as "no tie". It means a tuxedo is welcome but a dark suit is accepted.
  • Wearing a short dress to a black tie event
  • Wearing sneakers

Travelling in formal wear

A tuxedo and a gown wrinkle in bags. Use a garment bag or roll tissue in the folds, or hire at the destination. The wedding dress codes explained page covers more terms. For wedding trips abroad, see what to wear to a destination wedding abroad.
