- Blouse with sailor collar and white stripes
- Pleated skirt falling near the knee
- Ribbon or neckerchief at the front
Seasonal versions are issued: lightweight cotton for summer; wool blends for winter. Its “kawaii” (cute) appeal has been cemented by anime and manga.
1.2 Blazer Uniforms
Since the 1980s, many high schools have adopted Western-style blazers for a modern look.
- Tailored blazer with school crest
- White shirt and necktie or bow
- Plaid skirt for girls; trousers for boys

The gakuran jacket and matching trousers were inspired by Prussian cadet uniforms.
