The origin and evolution of pant

Pants(in North America) are an item of clothing worn from the waist to the ankles, covering both legs separately (rather than with cloth extending across both legs as in robes, skirts and dresses).

In the UK, the word "pants" generally means underwear and not trousers. Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower depending on the style of the garment. To distinguish them from shorts, trousers may be called "long trousers" in certain contexts such as school uniform, where tailored shorts may be called "short trousers", especially in the UK.

In most of the western world, trousers have been worn since ancient times and throughout the medieval period, becoming the most common form of lower-body clothing for adult males in the modern world, although shorts are also widely worn, and kilts and other garments may be worn in various regions and cultures. Breeches were worn instead of trousers in early modern Europe by some men in higher classes of society. Since the mid-20th century, trousers have increasingly been worn by women as well. Jeans, made of denim, are a form of trousers for casual wear, now widely worn all over the world by both sexes. Shorts are often preferred in hot weather or for some sports and also often by children and teenagers. Trousers are worn on the hips or waist and may be held up by their own fastenings, a belt or suspenders (braces).

Parts of pant

Pleats

Pleats just below the waistband on the front typify many styles of formal and casual trousers, including suit trousers and khakis. There may be one, two, three, or no pleats, which may face either direction. When the pleats open towards the pockets they are called reverse pleats (typical of most trousers today) and when they open toward the fly they are known as forward pleats.

Cuffs

Trouser-makers can finish the legs by hemming the bottom to prevent fraying. Trousers with turn-ups (cuffs in American English), after hemming, are rolled outward and sometimes pressed or stitched into place.

Fly

A fly is a covering over an opening join concealing the mechanism, such as a zipper, velcro or buttons, used to join the opening. In trousers, this is most commonly an opening covering the groin, which makes the pants easier to put on or take off. The opening also allows men to urinate without lowering their trousers.

Trousers have varied historically in whether or not they have a fly. Originally, hose did not cover the area between the legs. This was instead covered by a doublet or by a codpiece. When breeches were worn, during the Regency period for example, they were fall-fronted (or broad fall). Later, after trousers (pantaloons) were invented, the fly-front (split fall) emerged. The panelled front returned as a sporting option, such as in riding breeches, but is now hardly ever used, a fly being by far the most common fastening. Most flies now use a zipper, though button-fly pants continue to be available.

Trouser support

At present, most trousers are held up through the assistance of a belt which is passed through the belt loops on the waistband of the trousers. However, this was traditionally a style acceptable only for casual trousers and work trousers; suit trousers and formal trousers were suspended by the use of braces (suspenders in American English) attached to buttons located on the interior or exterior of the waistband. Today, this remains the preferred method of trouser support amongst adherents of classical British tailoring. Many men claim this method is more effective and more comfortable because it requires no cinching of the waist or periodic adjustment.
