Denier is a measurement of the thickness of the yarn used to make the hosiery. The higher the denier, the thicker the yarn and hence the more opaque the hosiery will be.0 denier hose are usually semi-opaque and 100 denier ones are opaque tights/pantyhose. However, there are also sheer tights/pantyhose that are of 100 denier as well. The higher the denier also means that the hosiery is also stronger and less likely to run easily.
