Dress uniform in the context of "Parade (military)"

A combat uniform, also called a field uniform, battledress, or military fatigues, is a casual uniform used by military, police, fire, and other public uniformed services for everyday fieldwork and duty, as opposed to dress uniforms for formal functions and parades. It generally consists of a jacket, trousers, and shirt or T-shirt, all cut to be looser and more comfortable than more formal uniforms. Combat uniform designs vary by regiment or service branch (e.g. army, navy, air force, marines, etc.). Uniform fabrics often come in camouflage, disruptive patterns, or otherwise olive drab, brown, or khaki monochrome, to approximate the background and make the soldier less conspicuous in the field. In Western dress codes, field uniforms are considered equivalent to civilian casual wear, less formal than service dress uniforms, which are generally for office or staff use, as well as mess dress uniforms and full dress uniforms.

Combat uniforms have existed to some degree in most organized militaries throughout history, with the intent of providing both protection and easy identification. The British Indian Army's Corps of Guides were the first to use drab combat uniforms starting in 1848, when they wore light-brown clothing called "khaki" by Indian troops. The Second Boer War and World War I ended the pre-modern practice of issuing brightly-colored combat uniforms in favor of green, brown, khaki, and grey uniforms that better suited the varied environments of modern warfare. The first proper military camouflage pattern was Italy's telo mimetico, originally designed for half-shelters in 1929. Germany's Wehrmacht began issuing camouflage uniforms to paratroopers during World War II, and by the end of the war, both the Allies and Axis made use of camouflage uniforms for select units, usually special forces. The Cold War and post–Cold War era saw the gradual shift from monochromatic olive and khaki combat uniforms to those using camouflage patterns.

A necktie (American English) – also called a long tie or, more usually, simply a tie (Commonwealth English) – is a cloth article of formal neckwear or office attire worn for decorative or symbolic purposes, knotted at the throat, resting under a folded shirt collar, and usually draped down the chest. On rare occasions neckties are worn above a winged shirt collar. Neckties are usually paired with collared dress shirts under suit jackets or blazers, but have often been seen with other articles, such as sport coats and v-neck sweaters. Neckties can also be part of a uniform, however, in occupations where manual labor is involved, the end of the necktie is often tucked into the button line front placket of a dress shirt, such as the dress uniform of the United States Marine Corps.

Neckties are reported by fashion historians to be descended from the Regency era double-ended cravat. Adult neckties are generally unsized and tapered along the length, but may be available in a longer sizes for taller people, designed to show just the wide end. Widths are usually matched to the width of a suit jacket lapel. Neckties are traditionally worn with the top shirt button fastened, and the tie knot resting between the collar points. Importance is given to the styling of the knot. In the late 1990s, Thomas Fink and Yong Mao of University of Cambridge mathematically determined 13 knots as "aesthetically" viable out of a possible total of 85, of which the commonest known are the four-in-hand, the Pratt, and the Windsor knots. The cut of the folded collar of the dress shirt is typically paired to the style of knot used. Neckties were originally considered "menswear", but are now considered unisex items in most Western cultures.
