The school uniform with a sailor-style collar worn by Japanese schoolgirls in middle school and high school. The standard uniform consists of a white blouse, a pleated skirt, and a red neckerchief, but there are as many variations as there are stars in the sky.
Serafukus are commonly worn with a ribbon or bow in lieu of the traditional neckerchief. The line between "neckerchief" and "bow" is blurry, as the bows worn with serafukus often aren't actually dedicated bows or bowties, but rather a neckerchief tied into a bow instead of its intended scarf-like shape.
A serafuku always includes a skirt. If a sailor-style top is paired with shorts or another bottom, sailor shirt should be used instead. In fact, sailor suits with shorts are the older, original style: in the Victorian and Edwardian eras, they were used as boys' suits, from which then the girls' uniform with a skirt was derived.
For colored serafuku tags, both the shirt and skirt must match in color to apply, but not the neckwear or sailor collar.
Sailor dresses should not be tagged as serafuku.
