A form-fitting garment is an article of clothing that tightly follows the contours of the part of the body being covered. Most form-fitting clothing is worn by females. A feature of Western societies is the popularity of form-fitting clothing worn by women, compared to equivalent male garments. These include t-shirts, shorts, and jeans. Some cultures and religious communities disapprove of form-fitting clothing, especially outerwear, which they consider to be immodest.
There are numerous types of clothing which typically are or which can be made form-fitting. For example, stockings, leggings, tights, and socks are usually form-fitting. Clothing used in dance and in exercise, such as leotards, unitard, and swimsuits, are usually form-fitting. Undergarments or foundation garments such as corsets, girdles, bodysuits, brassieres, and underpants are form-fitting to give a smooth line to the outer clothing.
Though many materials can be used to make form-fitting garments, the thinner materials, such as synthetic fibers, are the most commonly used, because of the smooth line that can be produced as well as their extra strength when pulled tight. Some fabrics cling to the skin or do so when wet, giving a form-fitting effect.
