A G-string or thong is a narrow piece of cloth or leather, or plastic that passes between the buttocks. It is attached to a band around the hips. It can be worn as a swimwear or underwear by both men and women. The difference between a G-string and a thong is that a G-string has less material between the legs. This makes it look like a string. Variants of the thong or G-string include the "V-string" and the "T-string".
