1970'S MOM JEANS
Designer denim had its genesis in the 1970s, but it was in the 1980s that it really took off, beginning largely with Brooke Shields' controversial "Nothing Gets Between Me and My Calvins" ad campaign for Calvin Klein. Throughout the '80s the style shifted toward a tapered leg with a loose top, a "tight-roll" or "peg leg" style, if you will. By the early '90s, people were over the tight leg and into a looser fit on the bottom, resulting in, generally, what we would consider a baggy pair of jeans.
