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

An undershirt is a piece of underwear covering the torso, while underpants (often pants in the United Kingdom), drawers, and shorts cover the genitals and often the buttocks.
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.
