The "USN Dixie cap" or the white sailor hat of the U.S. Navy is an iconic headgear that has been part of the uniform of American sailors since 1886. This hat is also known as the "Dixie Cup" because of its resemblance to a disposable cup. It is a white, round, flat flapless hat, originally made of canvas and later cotton, and worn by men in grades E-1 to E-6.
Besides the classic white "Dixie Cup" hat, which is the most famous, there is also a variant in blue color, but it is not seen as often. The blue version is worn mainly by the crew of U.S. Navy ships and by Marines. The design and function remain the same as the
white version, but the blue hat can sometimes be part of parade or ceremonial uniforms.
