Pantyhose (known as Tights in the UK) are tight fitting coverings of the body from the waist to the feet, normally worn by women. Like stockings they are usually made of nylon.

The term 'pantyhose' is exclusively American, referring to the combination of 'panties' (an American term for women's undergarment) with hosiery. The one-piece pantyhose was a substantial improvement that appeared in the 1960's because it provided a convenient alternative to separate underwear and hosiery.

In North America, the term tights is used to describe a garment similar to pantyhose, but which is thicker and more commonly worn by girls, dancers, and athletes.

Pantyhose are worn for a number of reasons. Sheer pantyhose that match the skin color of the legs can enhance the appearance of legs, making them look smoother. Darker pantyhose can enhance the legs by outlining the shape. Pantyhose also has practical use, as it can provide warmth in colder weather and let women go "bare-legged" even in the winter. Pantyhose can even enhance blood circulation by applying even pressure on the legs throughout the day.

Pantyhose are available in a wide range of styles. The sheerness of the garment, expressed as a numerical 'denier'/'dtex', ranges from 3 (extremely rare, very thin, barely visible) to 20 (standard sheer) up to 30 (semi opaque). The terms denier and dtex refer to the weight of the yarn in grammes at a standard length: for denier, it is 9,000, for dtex, 10,000 metres. Thus, 1 Denier = 1g of yarn when 9,000 metres long.

Pantyhose also come in a variety of colors, from gray/black or skin tone common in business wear to brightly colored styles fashionable among young women.

Most pantyhose are composed of nylon and spandex, which provides the elasticity and form fitting that this characteristic of modern pantyhose. Unfortunately, the nylon fabric is somewhat prone to tearing and it is common for very sheer hose to 'run' soon after snagging on something sharp.

Pantyhose worn for fashion have a standard construction. The top of the waist is a strong elastic. The part covering the hips (boxer/brief area) is composed of a thicker material than the legs. The gusset or crotch is also a stronger material, sometimes made of cotton. The legs of the pantyhose are made of the thinnest material which has a consistent construction down to the toes, which may be reinforced to guard against wear.
