Greaser jackets, often made of leather, are a popular style associated with the 1950s youth subculture known as the greasers. These jackets typically feature a fitted design, zippered front, and sometimes include embellishments like patches or studs. They are often worn over casual clothing and are known for their rugged, rebellious look. The greaser style is closely linked to classic American rock and roll music, as well as films like Rebel Without a Cause and The Outsiders. The jackets symbolize a sense of defiance and individuality, making them a lasting icon in fashion and youth culture.
