marinière

thumb|Marinière of the French Navy

A marinière (), or tricot rayé (; ), is a cotton long-sleeved shirt with horizontal blue and white stripes. Characteristically worn by quartermasters and seamen in the French Navy, it has become a staple in civilian French fashion and, especially outside France, this kind of striped garment is often part of the stereotypical image of a French person. It is also known as a Breton shirt, as many sailors in the French Navy were from Brittany.
