are trousers that become wider from the knees downward. Related styles include flare, loon pants and boot-cut/leg trousers. Hip-huggers are bell-bottomed, flare, or boot-cut pants that are fitted tightly around the hips and thighs.
Bell-bottoms became very fashionable for women in the mid 1960s in Europe and in North America by the late 1960s and much of the 1970s, both for men and women. By 1967, they went from high-fashion to become part of the hippie counter-culture movement in the late 1960s, together with love beads, granny glasses, and tie-dye shirts, even getting mentioned in popular music, such as Bell Bottom Blues" by Blues-Rock super-group Derek and the Dominos in the 1970s, they moved into the mainstream. Sonny and Cher helped popularize bell-bottoms in the USA by wearing them on their popular television show. However, they can be seen as early as 1964, in the concert film The T.A.M.I. Show, worn (white "flares" with a baby-doll top) by a young Toni Basil, who at the time was a go-go dancer.
