A body stocking 7179-D is a one-piece, form-fitting garment that covers the torso, legs, and sometimes the arms, resembling a blend of pantyhose and a leotard. Made from stretchy materials like nylon, spandex, or lace, it can be sheer or opaque and is often worn as lingerie, dancewear, or under clothing for a smooth silhouette. Some designs include open-crotch or built-in bras for versatility.
