A tuxedo is a form of men's evening formal wear, commonly called a tux in North America and a dinner jacket or black tie elsewhere. It is the standard outfit for many formal evening occasions and has a distinct set of components, fabrics and conventions that distinguish it from daywear and the more formal white-tie dress code.
Core components
A conventional tuxedo ensemble typically includes a tailored jacket with silk or satin-faced lapels, matching trousers, a white dress shirt, a bow tie, formal shoes and sometimes a waist covering such as a low-cut waistcoat or a cummerbund. Accessories often include cufflinks, studs, a pocket square and a boutonnière. For an overview of formalwear and its components see formalwear overview.
Shirts, ties and waist coverings
The dress shirt worn with a tuxedo is usually white and may be plain, pleated or textured; collars vary between wing and turndown styles. Typical shirt fabrics include cotton and linen, noted for breathability and comfort; see further notes on fabrics at dress shirt types and common fabric choices such as cotton and linen.
The bow tie is the traditional neckwear for black tie and is most often black for evening wear, though white or other colors appear in specific contexts. Bow ties are commonly made of silk or synthetic fabrics; read about material options at silk neckwear and synthetic alternatives. Waist coverings, whether a low waistcoat (vest) or cummerbund, provide a smooth front and are used according to personal style and the formality of the event; see guidance on waistwear at waistcoat and cummerbund.
Jacket and trousers
The jacket distinguishes a tuxedo from an ordinary suit through details such as satin-faced lapels, a single-breasted or double-breasted cut and often a slimmer, evening-oriented silhouette. Trousers are cut from the same cloth and traditionally have a narrow silk braid along the outer seam rather than the typical suit pocket trim. The most common colors are black and midnight blue; midnight blue can appear deeper under artificial light and is frequently favored for evening wear.
Accessories, footwear and optional items
Formal shoes are dark, polished leather—often patent—and should be simple and unobtrusive. Other optional items include a pocket square, studs and formal cufflinks, and in some traditions a top hat or gloves for highly ceremonial occasions. Historically and in some dress codes, white gloves are used for formal service or ceremonial roles; for a note on gloves see gloves and ceremony.
Occasions and usage
Tuxedos are traditionally worn for evening events that specify black-tie dress: weddings, galas, formal dinners, certain dances and award ceremonies. Some professions adopt tuxedos as a uniform for formal engagement, notably orchestral musicians and particular hospitality roles, because the outfit presents a uniformly formal and unobtrusive appearance. Guidance on when black tie is appropriate is available at wedding and event dress guidance and formal event etiquette.
History and regional names
The dinner jacket emerged in 19th-century Britain as a less formal alternative to the tailcoat and was adapted internationally. In the United States the garment became widely known by a name associated with a social club and locale; elsewhere the terms "dinner jacket" or simply "black tie" are more common. For concise histories and commentary see dinner jacket history and black tie evolution.
Fit, purchase, rental and care
Because most men wear tuxedos infrequently, rental services are common for one-off events while tailored purchases remain preferred by frequent wearers or professionals. Proper care includes professional cleaning and careful storage to preserve shape and the silk facings; alterations to trouser length, sleeve length and shoulder fit are often necessary for a correct silhouette. Practical advice on tailoring, rental choices and garment care appears at tailoring advice, rental considerations and care recommendations.
Variations and modern practice
Contemporary designers produce variations in cut, lapel style and fabric while many wearers continue to favor classic treatments. Color and fabric experiments are more common at fashion-forward events, but conservative black-tie remains the norm for formal evening affairs. Coordination between partners, for example matching a waistcoat or pocket square to a companion’s attire, is a frequent modern practice; see notes on coordination at fabric and color notes and style variations.
Readers seeking deeper historical detail or technical tailoring instruction should consult specialist menswear references and etiquette guides for authoritative, illustrated guidance on lapel shapes, shirt fronts and appropriate formality.
