Sailor hats, also known as navy caps or dixie cups, are a type of headwear traditionally worn by sailors in the navy. They are typically made of white cotton or polyester and feature a flat, circular top with a wide, stiff brim. The design is practical, providing shade from the sun and protection from the elements. These hats often have a black ribbon or band around the base, which can signify rank or branch of service. Sailor hats have become a popular fashion item beyond the military, often seen in nautical-themed clothing and accessories, symbolizing a maritime lifestyle.
