The form must first be comfortable. In addition, it should be beautiful . And yet a requirement. It should be in different versions, but not as much as it was in Soviet times. Brown dress on a girl , and only had a black apron for every day and white on the holiday. The current form is to allow the girl to have and a skirt and pants, and a variety of options for jackets, sleeveless jackets and blouses . For the boys , too, should have a choice . And not necessarily shirts and ties . Can be shaped and T-shirts with the logo of the school. And the uniform sweaters. And it would be better simply to determine each school cloth "top" and "bottom " , and then each necks out of it what you like.
