A mythical marine garment, La Marinière today represents French know-how... But more particularly, a Breton know-how. It is from the 18th century where its history begins. At its origin, this garment featured a long boat neck, and no stripes. It was in 1810 that the striped garment as we know it appeared under the name "striped knit". Made of jersey material, it originally served as undergarments for sailors.
Used predominantly by sailors near the English Channel and in Brittany, the striped knit allowed the sailors to move around more freely while avoiding the cold. It was just as importantly used to better spot sailors if they went overboard - three essential factors for its use when sailing.
21 - this the number of 20mm white stripes that must be present on the sailor's garment, according to the Decree of the French Navy of 1858. Prior to this decree, the dressing of sailors was not official - meaning they wore their own clothing on board. If we today refer to this striped garment as "La Marinière", it is simply in reference to the sailors who wore it.
