Girl In School Uniform Outfit

Italy
In Italy, school uniforms are uncommon, partially because child uniforms are associated with the era of Benito Mussolini before World War II when children were placed according to their age into Italian Fascist youth movements and had to wear uniforms inside and outside school.
However, until the early 1970s many high schools required girls to wear black grembiule (resembling a doctor smock) on top of their clothes: no uniform was required for boys. Perhaps this was because at one time high schools were the only public schools to admit both sexes (as opposed to junior schools and elementary), and girls may be required to "cover up" not to distract their male counterparts. Indeed this policy was highly disputed during the sexual revolution of the 1960s and later abolished.
Nowadays, many pre-schools advise parents to dress their children with a grembiulino, i.e., a small grembiule, usually shorter and more colourful, that can be purchased cheaply.
