What is the difference between Pantyhose and Tights : eBay Guides

Pantyhose are sheer and tights are more opaque. Stockings are measured in Deniers, a unit of density measurement for textile fibers. The lower the denier, the finer the yarn, the more sheer the stockings. The higher the denier, the more opaque the hosiery. Opaque tights also are heavier and warmer.
