When did everyone start wearing the peace sign?

The peace sign, originally designed in 1958 for the British nuclear disarmament movement, gained widespread popularity during the 1960s as a symbol of anti-war sentiment, particularly during the Vietnam War. It became synonymous with the counterculture movement, with many people adopting it as a symbol of peace and protest. By the late 1960s, the peace sign was commonly seen on clothing, posters, and jewelry, making it a prominent emblem of the era.
