Tights
From wipipedia.org
Tights are a tight-fitting garment covering the legs, hips and buttocks.
They usually cover the feet (ones that do not are called footless tights) and come up above the waist. Generally they are made from sheer (see-through) nylon, though opaque ones are common. However, they are also available in rubber.
They are usually regarded as a female garment, but are customarily worn by male ballet dancers.
