In Europe, it can be traced back to the Roman era in the 5th century BC. Pantyhose, also known as tight socks or stockings, is a clothing that tightly covers the body from the waist to the feet, and is mostly worn by women. Like stockings, there are many materials available, including cotton, nylon, wool blend, etc. Pantyhose appeared in the 1960s and became another optional form of stockings.
