Sheer pantyhose are the anchors of any hosiery wardrobe. They easily go from office to evening in all seasons. Typically, sheer pantyhose is offered in classic hues, like black, nude and off-black. Some styles have control tops to trim tummy and hips. Modern control tops can be completely sheer, offering invisible shaping. Pantyhose are usually made of nylon, often with spandex for stretch and shape retention. Sheerness is measured by the denier factor, which measures the thickness of the hosiery fiber. Deniers range from 8 to 100, with 8 being the sheerest and 100 being the most opaque. This is useful to know when buying pantyhose online.
