Sailor Collar

The square-backed collar from naval uniform to school uniform.

A sailor collar is a broad collar that lies flat across the shoulders, forming a square flap down the back and tapering to a V at the front, usually worn with a neckerchief or tie threaded beneath it. It comes directly from the uniform of nineteenth-century sailors and remains one of the most recognizable collar shapes in the world.

From Naval Deck to Classroom

Naval collars were practical before they were decorative: the square back panel protected the uniform from the tarred pigtails sailors once wore, and the loose shape could be grabbed as a handle in a man-overboard rescue, according to longstanding naval lore. Navies standardized the look in the 1800s, and children's clothing copied it almost immediately — the sailor suit became the default 'best' outfit for generations of children.

Its most famous afterlife is the Japanese school uniform, the sailor fuku, where the collar, scarf, and pleated skirt make up an iconic silhouette recognized worldwide.
