Bell-bottoms are a style of pants characterized by a fitted waist and thighs that flare out dramatically from the knee down. This design creates a distinctive "bell" shape at the bottom of the legs. Originally worn by sailors in the 19th century, they gained popularity in the 1960s and 1970s, becoming a symbol of the counterculture movement and disco fashion. These pants are often made from denim or cotton and can be paired with various tops, making them versatile for casual and semi-formal occasions. Bell-bottoms have seen a resurgence in recent years, appealing to both vintage enthusiasts and modern fashion trends, reflecting a nostalgic return to retro styles.
