Pantyhose, stockings, and tights are all types of hosiery that are worn on the legs. However, there are a few key differences between these three items.

Pantyhose, also known as sheer tights, are a type of hosiery that covers the whole leg, from the waist to the toes. They are usually made from a sheer, stretchy fabric that provides a smooth, polished look. Pantyhose are often worn with skirts and dresses to provide a layer of warmth and to give the legs a smooth, polished appearance.

Stockings, on the other hand, are a type of hosiery that covers only the foot and the lower part of the leg. They are typically made from a thicker, more durable fabric than pantyhose, and they do not have a built-in panty. Stockings are often held up by a garter belt or garter straps, and they are often worn with dresses and skirts.

Tights, also known as leggings, are a type of hosiery that covers the entire leg, from the waist to the toes. They are typically made from a thicker, more durable fabric than pantyhose, and they provide more coverage and warmth than stockings. Tights are often worn with dresses and skirts, as well as with shorts and tunics.

In summary, the main difference between pantyhose, stockings, and tights is the amount of coverage they provide. Pantyhose cover the entire leg, from the waist to the toes, while stockings cover only the foot and lower leg, and tights cover the entire leg.
