  • Publication number: 20100212072
    Abstract: A waistband for a pantyhose, a pantyhose including the waistband and a method of making the pantyhose. The waistband includes a cylindrical elastic material measured to cover body of a pantyhose wearer from a top of hip bone downward over the hip bone. Such a low-lying waistband covers the hip comfortably and is supported by the hip bone such that it does not cut into the softer parts of the abdomen to create pain in the skin and internal organs. Both the width and location of the waistband hold the pantyhose in place. The waistband continues downward from the top of the hip bone and ends substantially where the hip bone connects to the leg bone.
