Pants are a garment extending from the waist to the knees or ankles and divided into separate coverings for the legs: more formally called trousers. Pants can be worn by both men and women.
Trousers are an item of clothing worn from the waist to the ankles, covering both legs separately (rather than with cloth stretching across both as in skirts and dresses). The word trousers is used in the UK and Ireland, but some other English-speaking countries such as Canada, South Africa, and the United States can also refer to such items of clothing as pants, an abbreviation of the historic term pantaloon. Australia is known to differentiate between Pants and Trousers Additional synonyms include slacks, strides, kegs or kex, breeches (sometimes britches), or breeks. Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower than the knee depending on the style of the garment.
