In clothing design, a panty line on a human body goes at an angle from the high hip down to the crotch.[3] It is used as a reference line, for example, a babydoll can end either below or above the panty line (the latter option allows the companies to market a matching set with panties).[4] The term is also used for the edge of the panties, in particular when it is visible through the outer garment.[5]
