Weekend sunset dress
Formal wear, formal attire or full dress is the traditional Western dress code category applicable for the most formal occasions, such as weddings, christenings, confirmations, funerals, Easter and Christmas traditions, in addition to certain audiences, balls, and horse racing events. Formal attire is traditionally divided into formal day and evening attire; implying morning dress before 6 p.m., and white tie (dress coat) afterwards. Generally permitted other alternatives, though, are 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. In addition, formal attire may be instructed to be worn with official orders and medals.
With background in the 19th century, the protocol indicating particularly men's formal attire have remained virtually unchanged since the early 20th century, and remains observed so in certain settings influenced by Western culture: notably around Europe, the Americas, and Australia, in addition to Japan. For women, although fundamental customs for ball gowns (and wedding gowns) likewise apply, changes in fashion have been more dynamic. Optional conventional headgear for men is the top hat, and for women picture hats etc. of a range of interpretations.
