Hip-huggers are a style of pants worn by both men and women, generally made of denim and fitted tightly around the hips and thighs, while flaring out towards the lower leg. Hip-huggers were first designed by Irene Kasmer in 1957 in Los Angeles, California. They were worn by the mods in the mid 1960s and into the early 1970s. The late 1970s saw the return of hip-huggers in the disco scene. They went out of style again in the early 1980s, but made a reappearance in the 2000s. The hip-huggers of the 2000s were distinguished by the tightness of the knee, as well as the lower rise of the jeans, typically well below the belly button. This is the product of the boot cut style.
