In the 1960s and 1970s, girls were prohibited from wearing pants to school in many places. They were required to wear skirts or dresses, and the appropriate length was judged by having the girl kneel so that her skirt would hit the floor. However, by 1969 or 1970, girls were finally allowed to wear pants to school in some places. For example, a group of girls in Fargo-Moorhead held a "protest" in sixth grade at Horace Mann in 1970-71 and were finally allowed to wear pants.
