Suit in the context of "Haberdasher"

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 handkerchief (/ˈhæŋkərtʃɪf/; also called a hankie or, historically, a handkercher or a fogle) is a form of a kerchief or bandanna, typically a hemmed square of thin fabric which can be carried in the pocket or handbag for personal hygiene purposes such as wiping one's hands or face, or blowing one's nose. A handkerchief is also sometimes used as a purely decorative accessory in the breast pocket of a suit; it can then be called a pocket square. A handkerchief is also an important accessory in many folk-dances in many regions like the Balkans and the Middle East; an example of a folk-dance featuring handkerchiefs is the Greek Kalamatianós.

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

Casual wear (or casual attire or clothing) is a Western dress code that is relaxed, occasional, spontaneous and suited for everyday use. Casual wear became popular in the Western world following the counterculture of the 1960s. When emphasising casual wear's comfort, it may be referred to as leisurewear or loungewear.

While casual is "informal" in the sense of "not formal", informal wear traditionally refers to a Western dress code associated with suits—a step below semi-formal wear—thus being more formal than casual attire.

Service dress uniform is the informal type of uniform used by military, police, fire and other public uniformed services for everyday office, barracks and non-field duty purposes and sometimes for ceremonial occasions. It frequently consists of a jacket, trousers, dress shirt, and neck tie, along with orders, medals, and insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In Western dress codes, a service dress uniform is a permitted supplementary alternative equivalent to the civilian suit—sometimes collectively called undress or "dress clothes". As such, a service dress uniform is considered less formal than both full dress and mess dress uniforms, but more formal than combat uniforms.

Service dress uniforms were originally worn in active service in the field or at sea, but became relegated to office, barracks, and walking out dress as more practical field uniforms evolved. In some parts of some armed forces such as the British Army, service dress uniform may also be used for ceremonial occasions, gradually replacing in this role the full dress uniforms that had preceded them as field uniforms. In the United States Navy, for example, service dress uniforms are worn for official functions not rising to the level of full dress or mess dress uniforms. They are also commonly worn when travelling in official capacity, or when reporting to a command. They may be seasonal, with a white uniform worn in summer and darker versions in winter.
