Socks are manufactured in a variety of lengths. Bare or ankle socks extend to the ankle or lower and are often worn casually or for athletic use. Bare socks are designed to create the look of "bare feet" when worn with shoes. Knee-high socks are sometimes associated with formal dress or as being part of a uniform, such as in sports (like football and baseball) or as part of a school's dress code or youth group's uniform. Over-the-knee socks or socks that extend higher (thigh-high socks) are today considered female garments. They were widely worn by children, both boys and girls, during the late-19th and early-20th centuries., although the popularity varied widely from country to country.  When worn by adult females, knee-high or thigh-high socks can become the object of sexual attraction and fetishism by some men.
