"Overalls are trousers with an attached front patch covering the chest and with attached braces which go over the shoulders. Bib overalls are usually made of denim and often have riveted pockets, similar to those on jeans. Bib overalls have long been associated with rural men and boys in the U.S. South and Midwest, especially farmers and railroad workers. They are often worn with plaid flannel shirts, long johns or a red union suit underneath, or with a T-shirt or no shirt at all in warmer weather. Since the 1960s, different colors and patterns of bib overalls have been increasingly worn by young people of both sexes, often with one of the straps worn loose or unfastened along the side and under the arm. The bib overalls fashion trend among American youth culture peaked in the latter half of the 1970s."
