Bell-bottom pants are a style of trousers that flare out from the knee to the hem, creating a distinctive bell shape. They became popular in the 1960s and 1970s, often associated with hippie culture and disco fashion. These pants are typically made from denim or cotton and can be found in various colors and patterns. Originally worn by sailors in the 19th century, bell-bottoms gained mainstream popularity through music and film. Iconic figures like Jimi Hendrix and Farrah Fawcett helped to popularize the look. Today, bell-bottom pants are considered a retro fashion statement and are sometimes referred to as flared jeans.
