Firstly, a special teenage informal style
In Western Europe and the USA (at the end of the sexual revolution) so that schoolgirls would not attract the attention of men (especially those who are over thirty or forty!), thereby not straying from the true path and for the time being were not distracted from their studies and career. (And it really works! However, sometimes pedophiles are especially attracted to this style of clothing, for whom it is a particularly attractive bait...).
