Various schools are known for their particular uniforms. Uniforms can have a nostalgic characteristic for former students, and are often associated with relatively carefree youth. Uniforms are sometimes modified by students as a means of exhibiting individualism, including lengthening or shortening the skirt, removing the ribbon, hiding patches or badges under the collar, etc. In past decades, brightly coloured variants of the sailor outfits were also adopted by Japanese yankii and Bōsōzoku biker gangs.
Because school uniforms are a popular fetish item, second-hand sailor outfits and other items of school wear are brokered through underground establishments known as burusera, although changes to Japanese law have made such practices difficult. The pop group Onyanko Club had a provocative song called "Don't Strip Off the Sailor Suit!".
