The bell bottom pants became popular in the late 1960s and continued to widen into the ’70s as they gained in popularity. This was a time where polyester became a popular fabric to use in clothing. Also bold colors and prints became part of men’s fashion for the first time.
Early 1970s fashion was a fun era. It culminated some of the best elements of the ’60s and perfected and/or exaggerated them. Some of the best clothing produced in the 1970s perfectly blended the mods with the hippies.
Just when it seemed pants couldn’t flare any more, the flare was almost gone. By the late 1970s the pant suit, leisure suit and track suit was what the average person was sporting. Every man had a few striped v-neck velour shirts.
