Young Brunette Girl Reveals Her Red And Black Undergarments In The Park

Function
Underwear is worn for a variety of reasons. They keep outer garments from being soiled by perspiration, urine, semen, menstrual blood and feces. Women's brassieres provide support for their breasts, and men's briefs serve the same function for the male genitalia. A corset may be worn as a foundation garment to alter a woman's body shape. For additional support and protection when playing sports, men often wear more tightly fitting underwear, including jockstraps and trunks. Women may wear sports bras which provide greater support, thus increasing comfort and reducing the chance of damage to the ligaments of the chest during high-impact exercises such as jogging.
In cold climates, underwear may be an additional layer of clothing that helps the wearer keep warm. Underwear can be used to preserve the wearer's modesty – for instance, some women wear camisoles and slips (petticoats) under clothes that are sheer. Conversely, underwear can also be worn for erotic effect. It is possible to purchase underwear made specifically for sexual titillation, such as edible underwear and crotchless panties.
Some items of clothing are designed as underwear, while others such as T-shirts and certain types of shorts are suitable both as underwear and as outer clothing. The suitability of underwear as outer clothing is, apart from the indoor or outdoor climate, largely dependent on societal norms, fashion and the requirements of the law. If made of suitable material, some underwear can serve as nightwear or swimsuits.
