Young Brunette Girl Strips Her V-string Panties In The Red Kitchen

One type of thong is the G-string, the back of which consists only of a (typically elasticized) fabric string. The two terms G-string and thong are often used interchangeably; however, they can refer to distinct pieces of clothing. Thongs come in a variety of styles depending on the thickness, material, or type of the rear portion of fabric and are available for both men and women throughout most of the world.
Nomenclature
