White tie in the context of "Formal attire"

A tiara (from Latin tiara, from Ancient Greek τιάρα (tiára)) is a head ornament adorned with jewels. Its origins date back to ancient Greco-Roman world. In the late 18th century, the tiara came into fashion in Europe as a prestigious piece of jewelry to be worn by women at formal occasions. The basic shape of the modern tiara is a semicircle, usually made of silver, gold, or platinum and richly decorated with precious stones, pearls, or cameos.

Tiaras were extremely popular during the late 19th century and were worn at events where the dress code was white tie. After World War I, wearing a tiara gradually fell out of fashion, except for official occasions at a royal court. Interest in tiaras has increased again since the beginning of the 21st century. The word tiara is often used interchangeably with the word diadem.

A waistcoat (UK and Commonwealth, /ˈweɪs(t)koʊt/ or /ˈwɛskət/; colloquially called a weskit) or vest (US and Canada) is a sleeveless upper-body garment. It is usually worn over a dress shirt and necktie and below a coat as a part of most men's formal wear. It is also sported as the third piece in the traditional three-piece male suit. Any given waistcoat can be simple or ornate, or for leisure or luxury. Historically, the waistcoat can be worn either in the place of, or underneath, a larger coat, dependent upon the weather, wearer, and setting.

Daytime formal wear and semi-formal wear commonly comprises a contrastingly coloured waistcoat, such as in buff or dove gray, still seen in morning dress and black lounge suit. Traditionally, a white waistcoat is worn for white tie and a black one for black tie.

A top hat (also called a high hat, or, informally, a topper) is a tall, flat-crowned hat traditionally associated with formal wear in Western dress codes, meaning white tie, morning dress, or frock coat. Traditionally made of black silk or sometimes grey, the top hat emerged in Western fashion by the end of the 18th century. Although such hats fell out of fashion through the 20th century, being almost entirely phased out by the time of the counterculture of the 1960s, it remains a formal fashion accessory. A collapsible variant of a top hat, developed in the 19th century, is known as an opera hat.

Perhaps inspired by the early modern era capotain, higher-crowned dark felt hats with wide brims emerged as a country leisurewear fashion along with the Age of Revolution around the 1770s. Around the 1780s, the justaucorps was replaced by the previously casual frocks and dress coats. With the introduction of the top hat in the early 1790s, the tricorne and bicorne hats began falling out of fashion. By the start of the 19th century, the directoire style dress coat with top hat was widely introduced as city wear for the upper and middle classes in all urban areas of the Western world. The justaucorps was replaced in all but the most formal court affairs. Around the turn of the 19th century, although for a few decades beaver hats were popular, black silk became the standard, sometimes varied by grey ones. While the dress coats were replaced by the frock coat from the 1840s as conventional formal daywear, top hats continued to be worn with frock coats as well as with what became known as formal evening wear white tie. Towards the end of the 19th century, whereas the white tie with black dress coat remained fixed, frock coats were gradually replaced by morning dress, along with top hats.

Full dress uniform, also known as a ceremonial dress uniform or parade dress uniform, is among the most formal type of uniform used by military, police, fire and other public uniformed services for official parades, ceremonies, and receptions, including private ones such as marriages and funerals. Full dress uniforms typically include full-size orders and medals insignia. Styles tend to originate from 19th-century uniforms, although the 20th century saw the adoption of mess dress-styled full-dress uniforms. Designs may depend on regiment or service branch (e.g. army, navy, air force, marines). In Western dress codes, full dress uniform is a permitted supplementary alternative equivalent to the civilian white tie for evening wear or morning dress for day wear – sometimes collectively called full dress – although military uniforms are the same for day and evening wear. As such, full dress uniform is the most formal uniform, followed by the mess dress uniform.

Although full dress uniforms are often brightly coloured and ornamented with gold epaulettes, braids, lanyards, lampasses, etc., many originated in the 18th and early 19th centuries as normal styles of military dress that, with the adoption of more practical uniforms, were eventually relegated to ceremonial functions. Before World War I, most armed forces of the world retained uniforms of this type that were usually more colourful and elaborate than the ordinary duty (known as undress), or the active service dress uniform.

The lion comique was a type of popular entertainer in the Victorian music halls, a parody of upper-class toffs or "swells" made popular by Alfred Vance and G. H. MacDermott, among others. They were artistes whose stage appearance, resplendent in evening dress (generally white tie), contrasted with the cloth-cap image of most of their music-hall contemporaries.

According to Michael Kilgarriff, it was J. J. Poole, manager of the South London Music Hall, who first described the performer George Leybourne as "a Lion of a Comic". Victorian fashion then led to the use of the French words, lion comique, which in turn became a generic term for all performers with an imposing appearance and personality.

Morning dress, also known as formal day dress, is the formal Western dress code for day attire, consisting chiefly of a morning coat, waistcoat, and formal trousers for men, and an appropriate gown for women. Men may also wear a popular variant, where all parts (morning coat or waistcoat, and trousers) are the same colour and material, often grey, and usually called "morning suit" or "morning grey" to distinguish it; considered properly appropriate only to festive functions, such as summer weddings and horse races, which consequently makes it slightly less formal. The correct hat would be a formal top hat, or if on less spacious audience settings, optionally a collapsible equivalent opera hat.

Debrett's states that morning dress should not be specified as the dress code for events starting after 6 p.m. If a formal event will commence at or after 6 p.m., white tie should be specified instead. The semi-formal daytime counterpart of this code is the black lounge suit.

Black tie is a semi-formal Western dress code for evening events, originating in British and North American conventions for attire in the 19th century. In British English, the dress code is often referred to synecdochically by its principal element for men, the dinner suit or dinner jacket. In American English, the equivalent term tuxedo (or tux) is common. The dinner suit is a black, midnight blue or white two- or three-piece suit, distinguished by satin or grosgrain jacket lapels and similar stripes along the outseam of the trousers. It is worn with a white dress shirt with standing or turndown collar and link cuffs, a black bow tie, sometimes an evening waistcoat or a cummerbund, and black patent leather dress shoes or court pumps. Accessories may include a semi-formal homburg, bowler, or boater hat. In Britain, some individuals may rebel from the formal dress code by wearing coloured socks or a bow tie that is not black, such as red. For women, an evening gown or other fashionable evening attire may be worn.

The first dinner jacket is traditionally traced to 1865 on the then Prince of Wales, later King Edward VII (1841–1910). The late 19th century saw gradual introduction of the lounge jacket without tails as a less formal and more comfortable leisure alternative to the frock coat. Thus in many non-English languages, a dinner jacket is still known as the false friend "smoking". In American English, its synonym "tuxedo" was derived from the village of Tuxedo Park in New York State, where it was introduced in 1886 following the example of Europeans. Following the counterculture of the 1960s, black tie has increasingly replaced white tie for more formal settings in the United States, along with cultures influenced by American culture.
