Most UK schools allow girl pupils to wear trousers, but many girls still wear skirts in primary and secondary schools, even where the choice of trousers is given. In the late 20th century, many schools began changing their uniform rules to allow trousers for girls amidst opposition to skirts-only policies - the most publicised possibly being Jo Hale vs Whickam Comprehensive in 2000.[16] Although commonly accepted that girls may wear trousers to school, no test case is known to have been brought before the courts, making the legal position uncertain on requiring skirts as part of girls' uniforms. The rule is still enforced in many schools, particularly independent and selective state schools.
