Formal wear or full dress is the Western dress code category applicable for the most formal occasions, such as weddings, christenings, confirmations, funerals, Easter and Christmas traditions, in addition to certain state dinners, audiences, balls, and horse racing events. When formal dress is required, generally permitted alternatives include the most formal versions of ceremonial dresses (including court dresses, diplomatic uniforms and academic dresses), full dress uniforms, religious clothing, national costumes, and most rarely frock coats (which preceded morning coat as default formal day wear 1820s-1920s). In addition, formal wear is often properly worn when displaying official full size orders and medals.
The protocol specifying men's traditional formal wear has remained virtually unchanged since the early 20th century. Despite decline following the counterculture of the 1960s, it remains observed in formal settings influenced by Western culture: notably around Europe, the Americas, South Africa, Australia, as well as Japan. For women, although fundamental customs for formal ball gowns (and wedding gowns) likewise apply, changes in fashion have been more dynamic. Traditional formal headgear for men is the top hat, and for women picture hats etc. of a range of interpretations. Shoes for men are dress shoes, dress boots or pumps, and for women heeled dress pumps. In western countries, a "formal" or white tie dress code typically means tailcoats for men and evening dresses for women. The most formal dress for women is a full-length ball or evening gown with evening gloves. Some white tie functions also request that the women wear long gloves past the elbow.
