Grey jean skirts are usually made from cotton-blend denim. Common components include cotton (sometimes recycled cotton), polyester, rayon, and a small amount of spandex for stretch; some kids' styles are almost entirely cotton with a touch of spandex.
Care labels commonly recommend machine washing and tumble drying.
They commonly include front and back pockets plus details like a back yoke, belt loops, a coin pocket, and buttons or zippers. Skirtalls may also add adjustable straps.
Many grey denim skirts use midweight denim and are described as soft and stretchy, often because a small amount of spandex is added for comfort.
Kids' skirtalls include adjustable straps and side buttons.
