Sheer pantyhose is the hardworking staple of any hosiery wardrobe. A color close to your skin tone will create a sleek, polished look with any outfit, as well as highlighting shapely legs. Brands offer a good variety of colors, although the most popular remain various shades of nude and black. Sheer pantyhose is also available in lots of styles, including sheer-to-waist, control top, high waisted and even support hosiery. You'll find many finishes too--from a stylish matte finish to a silky sheen. The key factor in sheerness is denier, which measure the thickness of the fiber, from an 8 denier, which is the sheerest to 100 denier, which is the least sheer. The sheerest hosiery is often designated as ultra-sheer and will have a denier of 15 or lower.
