A G-string is a type of thong, a narrow piece of cloth, leather, or plastic, that covers or holds the genitals, passes between the buttocks, and is attached to a band around the hips. A G-string can be both worn by men and women. It may also be worn in swimwear, where it may serve as a bikini bottom, but may be worn alone as a monokini or topless swimsuit. G-strings may also be worn by exotic or go-go dancers. As underwear, a G-string may be worn in preference to panties to avoid creation of a visible panty line, or to briefs in order to enhance sex-appeal.
