In 1969, LIFE magazine set out to take pictures of the trends that had enthralled American youth, like hippies and disco culture. Their vibrant colors, varied materials, and casual disregard for all that was proper were all captured in these awesome photos. Though we possess unparalleled freedom today, many people’s fashion sense is still constrained. Consider the hipster: for all their counter-cultural claims, they are largely defined and even constrained by the mainstream that they oppose. Their disregard for the mainstream has become the mainstream.
