As in many other former British colonies, all South African private and public schools have a uniform, and it is compulsory in all public schools and in the vast majority of private schools for children above pre-school level. Uniform types vary less between public and private schools than they do across regions, where schools in more rural areas tend to forgo the daily wearing of ties and/or blazers for boys and girls regardless of their public or private nature. However, many of these same schools will have a "number ones" uniform for special occasions which include such items. In cities such as Cape Town, on the other hand, it is more common to see formal apparel required in public and private schools on a daily basis. Many schools across South Africa also provide the choice between a summer and winter uniform, with khaki uniforms and brown shoes being very common in the summer. Although many schools allow girls to also wear trousers (especially during winter months) South African law has not required gender neutrality in school dress codes and a distinction between girls' and boys' uniforms remains. Boys of all ages are normally required to wear grey or khaki long or short trousers with socks, and the socks are usually long when worn with shorts, as in the illustration (right). Until recently, the straw boater was a common accessory in affluent public and private high schools, although these have now become optional in some cases. Nearly all schools, public or fee paying, have sports' kits (uniforms) that often allow bare feet for junior schools, regardless of the season. Almost all South Korean secondary students wear a uniform called ""gyobok"" (Korean: 교복, 校服). The majority of elementary schools, except some private ones, do not have uniforms; however, the uniform is strictly monitored from the start of middle school and up. Based on Western-style ones, the South Korean uniform usually consists of a shirt, blazer and tie, with skirts for girls and trousers for boys. More recently, the uniform is often worn by celebrities who target the younger, teen audience to sell entertainment products. The school uniform and school setting is frequently used as a venue for romance. As a result, the uniform has become something akin to an expression of fashion among students. Name tags that are worn usually have different colours per grade. Oftentimes the writing is in black or white, whereas the background is coloured. In Spain the use of school uniforms is not compulsory in the public school at any stage.
