A panty consisting of a triangular patch of fabric connected with thin, elastic straps in back and around the waist completely exposing the buttocks. The lingerie g-string is a type of thong. The g-string straps are thinner than a thong. The appeal of a g-string is that the fabric passing through the crotch and up the buttocks is so thin as to appear to disappear, thus providing the appearance that no underwear is being worn from behind. G-strings typically have spaghetti strap style sides.
