Do any American schools have school uniforms that look like Japanese uniforms?

Some schools do. These uniforms often consist of a white, light blue, or navy colored shirt with long or short sleeves, a sailor-style collar, and a skirt or shorts for girls and pants for boys. Ties may be worn with the shirts, and blazers or vests may also be part of the uniform. While these uniforms may resemble Japanese school uniforms, they are not exact replicas and may vary in design and color.
