A suit jacket, also called a lounge jacket, lounge coat or suit coat, is a jacket in classic menswear that is part of a suit.

The black lounge suit (UK), stroller (U.S.), or Stresemann, is a men's day attire semi-formal intermediate of a formal morning dress and an informal lounge suit; comprising grey striped or checked formal trousers, but distinguished by a conventional-length lounge jacket, single- or double-breasted in black, midnight blue or grey. This makes it largely identical to the formal morning dress from which it is derived, only having exchanged the morning coat with a suit jacket, yet with equivalent options otherwise, such as necktie or bowtie for neckwear, a waistcoat, French cuffs dress shirt of optional collar type, and black dress shoes or dress boots. The correct hat would be a semi-formal homburg, bowler, or boater hat. Just as morning dress is considered the formal daytime equivalent of formal evening attire dress coat i e. white tie, so the stroller is considered the semi-formal daytime equivalent of the semi-formal evening attire dinner jacket, i.e. black tie. Unlike other dress codes, there is no clear equivalent for women, though typical morning dress and cocktail dress have both been identified as alternatives.

Black tie is a semi-formal Western dress code for evening events, originating in British and 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 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, typically 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. For women, an evening gown or other fashionable evening attire may be worn.
A blazer is a type of jacket resembling a suit jacket, but cut more casually. A blazer is generally distinguished from a sport coat as a more formal garment and tailored from solid colour fabrics. Blazers often have naval-style metal buttons to reflect their origins as jackets worn by boating club members.

Business casual is an ambiguously defined Western dress code that is generally considered casual wear but with smart components of a proper lounge suit from traditional informal wear, adopted for white-collar workplaces. This interpretation typically including dress shirt, necktie, and trousers, but worn with an odd-coloured blazer or a sports coat instead.

A double-breasted garment is a coat, jacket, or vest with wide, overlapping front flaps which has on its front two symmetrical columns of buttons; by contrast, a single-breasted item has a narrow overlap and only one column of buttons. In most modern double-breasted coats, one column of buttons is decorative, while the other is functional. The other buttons, placed on the outside edge of the coat breast, allow the overlap to fasten reversibly, left lapel over right lapel. To strengthen the fastening, a functional inner-button, called the jigger, is usually added to parallel-fasten the over-lapped layers together from the inside.

The Nehru jacket is a hip-length tailored coat for men or women, with a mandarin collar, and with its front modelled on the Indian achkan or sherwani, a garment worn by Jawaharlal Nehru, the Prime Minister of India from 1947 to 1964.

A Norfolk jacket is a loose, belted, single-breasted tweed jacket with box pleats on the back and front, with a belt or half-belt. It was originally designed as a shooting coat that did not bind when the elbow was raised to fire. Its origin is uncertain but it may have been named after Coke of Norfolk, the Duke of Norfolk, or after the county of Norfolk. It was made fashionable after the 1860s in the sporting circle of the Prince of Wales, later Edward VII, whose country residence was Sandringham House in Norfolk. The style was long popular for boys' jackets and suits, and is still used in some uniforms.

Most jackets have a variety of inner pockets, and two main outer pockets, which are generally either patch pockets, flap pockets, or jetted pockets.

A single-breasted garment is a coat, jacket, vest, or similar item having one column of buttons and a narrow overlap of fabric. In contrast, a double-breasted coat has a wider overlap and two parallel rows of buttons. Single-breasted suit jackets and blazers typically have two or three buttons, and a notch lapel. However, from the 1930s onwards, peaked lapels on a single button jacket have been variably in fashion. The width of the lapels is one of the most changeable aspects of the jacket, and narrow peak lapels on single-breasted jackets became popular during the 2000s.
Smart casual is an ambiguously defined Western dress code that is generally considered casual wear but with smart components of a proper lounge suit from traditional informal wear. This interpretation typically includes dress shirt, necktie, trousers and dress shoes, but worn with an odd-coloured blazer or a sports coat instead.

A smoking jacket is an informal men's style of lounge jacket originally intended for tobacco smoking, designed in the 1850s. A classic-styled smoking jacket comes in a shawl collar, turn-up cuffs, toggle or button fastenings, or simply be closed with a tie belt. It is usually made from velvet, silk, or both.

A sport coat, also called a sport jacket, is a men's smart casual lounge jacket designed to be worn on its own without matching trousers, traditionally for sporting purposes. Styles, fabrics, colours and patterns are more varied than in most suits; sturdier and thicker fabrics are commonly used, such as corduroy, suede, denim, leather, and tweed.

A Teba jacket is a soft, single-breasted jacket, unpadded throughout the chest and shoulders, and featuring shirt-like sleeves, ventless backs, and notchless lapels. It generally has four front buttons, either in leather or nacre.

Tracht refers to traditional garments in German-speaking countries and regions. Although the word is most often associated with Bavarian, Austrian, South Tyrolian and Trentino garments, including lederhosen and dirndls, many other German-speaking peoples have them, as did the former Danube Swabian populations of Central Europe.
